Free Will – Synopsis

The physicist Freeman Dyson once said: “…mind is already inherent in every electron, and the processes of human consciousness differ only in degree but not in kind from the processes of choice between quantum states which we call ‘chance’ when they are made by electrons.” In this essay, we assume Dyson was correct in his conjecture and explore the consequences. We start by supposing that a 1st person perspective exists in fundamental particles, like the electron, and that a duality exists between this and the 3rd person quantum mechanical description – two equivalent but different perspectives. For example, when electrons are fired through a Stern-Gerlach apparatus quantum mechanics says we will find the electron spin “up” a certain percentage of the time, and spin “down” the rest with nothing in between possible. From the electron’s perspective, it is forced to make a choice, with quantum probabilities manifesting as preferences for “up” vs “down”. In this way, the laws of quantum mechanics are followed precisely, the electron freely makes a choice in accordance with its preferences and the dual views agree. However, much is missing from the electron’s experience when contrasted with human consciousness: the electron has choice forced upon it – we fired it through the Stern-Gerlach apparatus – it cannot choose to not make a choice, it has no means to retain memories, no self-awareness, no mind’s eye, etc. Furthermore, electrons are interacting with the environment and being forced to make choices at a maddening rate of billions of times per second. With quantum entanglement things begin to change, however. Quantum entanglement is the only process within physics by which two or more fundamental particles can become “One system” of particles in a meaningful way. And, in practice, billions of particles have been entangled with no theoretical upper bound. We use recent theorems of quantum mechanics that show how sustained quantum entanglement in biological systems is possible despite fast decoherence rates. As entanglement grows more extensive we show how memory emerges in the entangled system, and how choices become possible without collapsing the system, while adding the vast computational power of a quantum system. At a certain point entanglement becomes so extensive that the system’s wave function interacts with itself forming a crisscross topology. This self-interaction gives rise to a nonlinear Schrödinger equation, which has known solutions, e.g. Davydov solitons and Fröhlich condensates. Such a nonlinearity may allow NP-complete problems to be solved in polynomial time. The crisscross entanglement topology is conceptually like the system regulating its’ own magnetic field ala’ the Stern-Gerlach apparatus. From the 1st person perspective this feels like the “mind’s eye” and allows the system to choose what choices to make – and whether to make a choice or not. This gives rise to free will. We show that all of this is consistent with the latest experimental results from Biology and Neuroscience. Our results paint a compelling picture of the evolution of life as a phenomenon of growing quantum entanglement in which more advanced conscious phenomena, like memory, self-awareness, a mind’s eye, and free will emerge with, and dual to, growing quantum entanglement. We further consider recent theories showing how quantum entanglement among the electron clouds in DNA stabilizes the molecule. We explore the consequences if such stabilizing effects can be extended to entanglement throughout organisms. If true, we can offer a natural, compelling explanation, in quantum mechanical terms, of a great number of subjective phenomena – the feeling of Oneness of the organism, stress, meditation, sex, understanding, self-awareness, empathy, moral responsibility, qualia of the senses, vice, love and consciousness. Furthermore, this would be a potential solution to the so-called combination problem of panpsychism, a variant form of the hard problem of consciousness.

I, Quantum

“It is remarkable that mind enters into our awareness of Nature on two separate levels. At the highest level, the level of human consciousness, our minds are somehow directly aware of the complicated flow of electrical and chemical patterns in our brains. At the lowest level, the level of single atoms and electrons, the mind of an observer is again involved in the description of events. Between lies the level of molecular biology, where mechanical models are adequate and mind appears to be irrelevant. But I, as a physicist, cannot help suspecting that there is a logical connection between the two ways in which mind appears in my Universe. I cannot help thinking that our awareness of our own brains has something to do with the process which we call ‘observation’ in atomic physics. That is to say, I think our consciousness is not just a passive epiphenomenon carried along by the chemical events in our brains, but is an active agent forcing the molecular complexes to make choices between one quantum state and another. In other words, mind is already inherent in every electron, and the processes of human consciousness differ only in degree but not in kind from the processes of choice between quantum states which we call ‘chance’ when they are made by electrons.” – Freeman Dyson, Physicist

I. The Question of Free Will

Do you believe in free will? Are you free to choose what you think, say, and do? Or, are your decisions the result of molecular interactions in your body, governed by the laws of physics, over which your control is merely illusory? Democritus (c. 460 – 370 B.C.) was the first to formalize this latter view, called determinism. He and his mentor, Leucippus, “claimed that all things, including humans, were made of atoms in a void, with individual atomic motions strictly controlled by causal laws” leaving no room for free will. He said, “by convention color, by convention sweet, by convention bitter, but in reality, atoms and a void” (via Wikipedia). Aristotle (384 – 322 B.C.), on the other hand, was the first to argue for the former perspective. In The Nicomachean Ethics he “lays out which actions deserve praise and which do not…” suggesting “we are in some way responsible for our actions” (from classicalwisdom.com) and alludes to free will. Shortly thereafter, Epicurus argued that as atoms moved through the void, there were occasions when they would ‘swerve’ from their otherwise determined paths, thus initiating new causal chains. Epicurus argued “that these swerves would allow us to be responsible for our actions, something impossible if every action was deterministically caused” from Wikipedia. Epicurus “did not say the swerve was directly involved in decisions, but, following Aristotle, he thought human agents have the autonomous ability to transcend” (causal laws) from Wikipedia. Philosophers and scientists would go on to debate free will for the next two thousand years, some for, and some against, and continue to do so to this day – with no resolution on the matter…

All of us feel that we have control of our choices. You certainly feel you have the power to continue or stop reading this essay if you so choose. It may, therefore, come as a surprise to you to know that many scientists and most physicists think that free will is just an illusion. Generally, they believe that your actions are governed by the laws of fundamental physics, which, in turn, describe the behavior of molecules, which, in turn, describe the behavior of neurons in your brain, which, in turn, determine your behavior. Their rationale can be summarized in the following two points:


First, scientists have been extremely successful at reductionism – finding a simple description of the world where a huge collection of phenomena, from the smallest scales of atoms to the largest scales of the Universe itself, can be explained in terms of a short list of 17 fundamental particles, and just four forces (see “Quantum Fields, the Real Building Blocks of the Universe” by David Tong (2017) for more). Whether we are talking about general relativity (large scale) or quantum mechanics (small scale), predictions of physics equations made long ago continue to be experimentally validated. For example, gravitational waves, predicted by the equations of general relativity in 1916, have recently been detected. They require an enormous four-kilometer-long apparatus, called LIGO, so sensitive it can detect movements of a billionth of a billionth of a meter (10^{-18} ). Similarly, the predictions of quantum mechanics have been experimentally validated time and time again. For example, the quantum mechanical prediction of the magnetic moment of an electron has been verified to 11 decimals places (see here for more). Given these foundations, reductionism describes a world in which these rigorous fundamental laws determine the behavior of atoms which determine the chemistry of molecules from which emerge the behavior of biological organisms and so on right up to the entire workings of our own minds – a tree, if you will, with its roots in physics, upon which chemistry and then biology are built. In this video (2013) physicist Sean Carroll likens the emergence of free will to the emergence of temperature in a room full of molecules. No single molecule has a temperature, molecules have kinetic energy, but looked at collectively they do. Temperature derives from the average kinetic energy of molecules. And, temperature is obviously very useful in describing the world around us. Similarly, in this video another physicist, Max Tegmark (2014), compares the emergence of free will to the emergence of the property of wetness from water – no single water molecule has the property of “wetness”, but collectively, water obviously does. The reductionist view is extremely compelling to scientists and receives such widespread acceptance it can feel like dogma.

Second, even though living organisms seem starkly different from all the inanimate matter in the reductionist tree, recent experiments in neuroscience have seemingly directly reinforced the reductionist view. In the 1980’s neurologist Benjamin Libet performed experiments on patients (Libet’s experiments) and observed that a “readiness potential” (RP), an EEG based measure of activity, in the motor cortex of the brain was correlated with actions like lifting a finger. The subjects were shown an easy-to-read visualization of a clock (see Libet’s clock here) and were asked to report the time shown when they decided to lift their finger. When the time reported by the subjects was compared with the timing of the readiness potential, it was found the RP increased a few hundred milliseconds before the subject reported making the decision. This suggested that the RP was determining the patient’s actions and, therefore, that their feeling of free will was illusory. More recently, neuroscientists have been able to insert electrodes into the brains of living patients and record the firings of individual neurons – see this TEDx video “Free Won’t” by Moran Cerf (2015). With the electrodes still hooked up to the patient, neuroscientists predict when and which button she will choose to press. The video shows the patient trying to outwit the machine, but it seems to know which button she intends to press before she can do so! (see more in Fried et al. (2010) and Soon et. al. (2008)) Such results suggest that actions might be deterministically predictable, and, if that is true, then there is no room for free will, right?


Still, there is something that feels incomplete about this rational, reductionist, objective description of the world. Perhaps the trouble with it is just that – it is objective! Consider this: even if there is neural activity that predicts simple action, and, even if there are many examples of properties in Nature that emerge, science only offer a description of this deep, rich subjective 1st person experience and this empowering feeling of free will in the 3rd person! The claim that the subjective experience emerges at some point feels arbitrary and trivial. Think about Isaac Asimov’s famous sci-fi novel “I, Robot”. If it was instead named “Wet Robot”, or “Square Robot”, or “Hot Robot”, it just wouldn’t have had anywhere near the same affect! Well, ok, you might have thought for a second about Hot Robot until you realized I was just talking about temperature! All kidding aside, there is a profound difference there. Something much deeper is going on. There are powerful subjective sensual qualities to life’s experiences which simply are not addressed in the scientific framework. Nobel prizing winning physicist, Erwin Schrödinger, in his book ‘What is Life?‘ (1944), had this to say:


“In this chapter I have tried by simple examples, taken from the humblest of sciences, namely physics, to contrast the two general facts (a) that all scientific knowledge is based on sense perception, and (b) that none the less the scientific views of natural processes formed in this way lack all sensual qualities and therefore cannot account for the latter“. – Erwin Schrödinger, What is Life? (1944)


Times have certainly changed regarding physics as the “humblest of sciences”, but Schrödinger’s point is as true today as ever! The reason science can’t say anything about this essential quality of life is as physicist Sean Carol specifically says (here): “we (scientists) realized that we are not smart enough to learn about the world just by thinking about it, we have to go out and look at it”. That’s all well and good for scientific objectivity, but, when we invoke this modus operandi, we are necessarily looking at the world from the 3rd person perspective. Never will you see in a scientific journal articles like: “How it feels when I subject myself to a THz laser“! (although we look forward to this paper: “What is it like to see entanglement?“) Here is Sean debating Alan Wallace, a Buddhist scholar, who charges “introspection plays no role in modern science”: “The Nature of Reality: A Dialogue Between a Buddhist Scholar and a Theoretical Physicist“. Wallace is correct. If we want to understand where our internal, 1st person perspective comes from, and our apparent free will, we are forced to undertake a subjective exploration. That’s not to say we want to abandon the external, objective success of science – we want to supplement it! Can we do both? Suppose we could reconcile the 1st person experience with the 3rd person description of science as dual views of the same thing? That is, suppose it is possible to follow all the laws of physics and have free will…

II. Dualities

Dualities are common in science. In the field of linear programming (LP), for example, a mathematical optimization problem involving 20 variables and 10 constraints in its primal form can be transformed into its dual form consisting of 10 variables and 20 constraints. Sometimes LP problems are easier to solve in their dual rather than primal form. Since they are dual to each other, if you solve one you solve the other. This technique is the secret behind Support Vector Machines in machine learning, and how they overcome the so called “curse of dimensionality“. Certain machine learning problems involving, say, hundreds of thousands of input variables (e.g. pixels), but far fewer examples, can be solved in their dual form much more easily.


Figure 3: Black hole diagram showing event horizon and singularity at the center – the subject of the AdS/CFT duality from UCSD Center for Astrophysics and Space Sciences


Einstein‘s theory of relativity is essentially a theory about dual descriptions of the world depending on one’s reference frame. A clock moving at near the speed of light will appear to slow to a crawl to a stationary observer, but an observer moving along in the same reference frame as the clock will see time pass normally. Reconciling these two reference frames is the work of the Lorentz transformations and they always do reconcile. Today, one of the most exciting dualities in science is the research in theoretical physics concerning the AdS/CFT duality. In this duality, one can use quantum field theory (Conformal Field Theory or CFT) to describe the quantum entanglement of particles on the boundary surface of a spacetime – like at the event horizon of a black hole, or, one can use gravity to describe spacetime curvature (Anti-de Sitter space or AdS) in the interior (the Bulk) and get the exact same results (see this video by Leonard Susskind for a simple explanation). Coincidence? The two theories are independent from each other, and have stumped physicists for nearly one hundred years as to how to unify them. But, now we are getting our first hints of how they come together – it now seems they offer descriptions of the Universe that are dual to each other. Two ways of describing the same thing. Two perspectives on the same phenomena. Certain problems in black hole research are easier to solve from the gravity perspective, and others are easier from the quantum field theory perspective. Since they are dual to each other, if you solve one you solve them both.


Descartes’ was the first to talk about a duality as it relates to the subjective 1st person experience (see Mind-Body Dualism). In his description, there was mind “stuff” (res cogitans) and matter “stuff” (res extensa). He believed that humans possessed this mind stuff but that animals were mindless machines saying: “without minds to direct their bodily movements…animals must be regarded as unthinking, unfeeling, machines that move like clockwork.”. In the argument we will follow in this essay, we are not looking at the 1st person/3rd person duality in the Cartesian sense, i.e. we are not talking about a dualism between a non-material spirit and matter as two separate things, but, rather, are looking at the problem as reconciling two views of the same underlying physical matter and processes, governed always by the laws of physics. One of these views is internal and subjective, the other external and objective, and represent, like the dualities in linear programming, Relativity Theory, and AdS/CFT, two ways of describing the same thing.


When we speak to others we have a subjective, 1st person experience of what it is like to be us speaking to them. We are perhaps happy, nervous, relieved, angry, or some complex mixture of these emotions and more. The conversation may be an easy one to have or a difficult one. Those listening to us have a 3rd person description of us speaking too. They may notice what we said, how we appeared while speaking. They may describe our speech as sad, excited, or some complex mixture of adjectives. If they attach electrodes to the neurons of our brain, they can provide an even more detailed objective description of us, but it still will be only that – an objective description. And, all this works vice-versa as well: our objective description of them, and, for each, their subjective experience of being themselves. These two descriptions of the same phenomenon, are dual to each other – they are two alternative ways of describing the same interaction. A subjective/objective, internal/external, 1st person/3rd person duality. Furthermore, we readily trust that others have this 1st person perspective even though we will never be able to experience it for ourselves. We will never be able to be them. Nor will we be able to prove that they are indeed having a subjective experience, yet it does not seem like a reach to believe it. In the same sense, we hope to make a plausible, circumstantial, and compelling case for free will even if we will never be able to prove it.


The problem of bridging the gap between the 1st and 3rd person perspectives is known as the “hard problem of consciousness” and was coined by the philosopher David Chalmers in his book “The Conscious Mind: In Search of a Fundamental Theory” (1996). However, here we are specifically not talking about the deep and complex subject of human consciousness. Human consciousness is characterized, I think we can all agree, by several things including: a 1st person perspective, choice and a sense of free will, a sense of self/self-awareness, a memory of the past, expectations of the future, qualia of the senses, emotions, a feeling of life, an awareness of death, and so on. Here, for starters, we want to approach a watered-down version of the hard problem of consciousness and only talk about the first two items in the list: a 1st person perspective and choice.


But, before we can dive in, we will need to talk about quantum mechanics and indeterminism. The scientific world outside of quantum mechanics is entirely deterministic. Take the case of the planets in our solar system: once we specify the initial coordinates, momenta, and a gravitational constant, the future orbits of all those planets are precisely determined. That is because the General Theory of Relativity, which describes gravity, is entirely deterministic. At the macroscopic level, the level of electrical circuits and bar magnets, determinism applies to electromagnetism as well. The equations of chemistry are mostly deterministic too. But, when we look really closely at the natural world, down to the level of quantum mechanics, we see a world that is indeterminant, governed by probabilities. On macroscopic scales these quantum probabilities average out and so the world appears deterministic – for example the trajectory of a baseball, or a rocket, appears precisely predictable. But, look up close at the atom and we can only calculate probabilities of finding, say, an electron, in a certain location, and nothing more than probabilities. The picture of the atom is not one of electrons orbiting a nucleus analogous to our solar system. Rather, fluctuating quantum waves of the spherical harmonics (along with a radial component) describe the location of the electrons and do so only probabilistically. It doesn’t appear there are any hidden variables either (see Bell’s theorem for more). That is, it is not that our description of the atom is incomplete. It is simply that, at its most fundamental level, the Universe is indeterminant. Still, these probabilities are governed precisely by quantum mechanical wave functions and it is not clear, even with indeterminism, how free will might enter into the laws of physics. In fact, physicists have argued specifically that the indeterminism of quantum mechanics does not imply free will. Their argument is based on the belief that (a.) quantum fluctuations are too small to affect decision making in the brain, and (b.) that there is no freedom in quantum mechanical laws – the outcomes of experiments are generated randomly as specified by the wave function in a probabilistic sense. However, recent theoretical and experimental developments in quantum biology, and a new perspective on randomness, which we will describe here, will open the door and allow free will to exist and to be understood in compliance with physical law. To proceed further, however, we first must introduce the reader to some of the concepts of quantum mechanics and how they may impact biological systems.

III. About Quantum Mechanics & Biology

We’ll start with the assumption that the laws of physics are sufficiently correct as written. Sufficiently correct means that for purposes of reconciling to our 1st person experience we don’t need to discover any new physics, such as a 5th force, or any new secret particle. The laws of physics may be refined in the future, sure, but for our purposes here we’ll assume we’ve got conceptually everything we need and see where we can go with it. This is particularly important regarding quantum mechanics. Quantum mechanics is one of the most successful, most validated, and most accurate theories ever. But, it is an especially weird subject matter and nothing we can say here can make it intuitive or sensible. The hard truth is, when we look up close at the Universe, things look very different than the reality we are accustomed too. One strange concept, called quantum measurement, connects the observer with the observed in an intimate way. For instance, the angle from which we look at an electron affects the direction it is spinning. Without touching, or otherwise disturbing the electron, the mere direction from which we view it affects the state it will be in! Now, the observer does not have to be a person, it can be any macroscopic device, such as a computer, a camera, photomultiplier tube, something called a Stern-Gerlach apparatus, and much more.


To this day, there is no scientific consensus about how to interpret the strange nature of quantum mechanics. However, very recently results have finally shed light on this problem. This paper, entitled “Understanding quantum measurement from the solution of dynamical models” by A. Allahverdyan et al. (2013) has shown how quantum measurement can be understood. The paper describes some very complex mathematics, yet, a conceptually simple framework and involves some things called quantum dynamical models, statistical mechanics, and “asymptotic cascades to pointer states“. It also describes how quantum measurements occur without any abrupt or time-irreversible
collapse of the wave function. When the coupling between the measuring apparatus and the system is dominant, the system entangles with the measuring apparatus and then cascades to a pointer state registering the measurement, but, when the coupling to the environment dominates, decoherence occurs (when information about the system leaks into the environment). We won’t dwell on the lengthy mathematical details but encourage the interested reader to dive in as this paper is tantamount to a sensible interpretation of quantum mechanics. For our purposes, it will be a sufficient approximation to follow the Copenhagen interpretation and view observation as causing the wave function of the observed to collapse (see Born rule). The wave function will collapse to states dictated by the measurement device (called basis states). This strange point connecting the observer and the observed will turn out to be essential to our attempts to reconcile the 1st and 3rd person perspective, so, below we give a, hopefully, illustrative example.


Suppose we place an electron in a toy box through a door in the top as shown in (figure 4). The electron is spin “up” (spinning in a right-handed way about an axis as depicted by the arrow – the arrow points along the axis of rotation like an axis between the north and south poles of the Earth). Technically, electron spin is a little bit more complex than this description, but, for our purposes, this will suffice to illustrate the concepts involved (the interested reader can dive in deeper to electron spin here). Next, we close the door, and open another door on the front side of the box. Fifty percent of the time the electron will be found pointing toward us (out of the page), and the other fifty percent away from us. There is no way to determine definitively which direction (toward or away) the electron will be spinning, all we can calculate are the probabilities. Whichever side of the box we open, that will determine the axis about which the electron is spinning. If we open a side door, the electron will be found spinning about that axis – toward or away with equal probability. However, if we place the electron in the box through the top, close the door, then re-open the top door, the electron will still be in the same state we left it with near one-hundred-percent probability.




Figure 4: A spinning electron is inserted through the top of a box with spin pointing up (counter-clockwise rotation about the axis). The door is closed. A door on the front is then opened. The electron can only be found pointing toward the observer or away. In this case, it will do so with 50/50% probability. The side of the box that we open determines the axis of the electron – a strange aspect of quantum mechanics that intimately connects the observer with the observed.


Our toy box is a metaphor for a spinning electron in a magnetic field. In the laboratory, electrons may only have spin +1/2 \hbar or -1/2 \hbar (where \hbar = Planck’s constant / (2pi)^{1/2} ). Nothing in between is allowed by Nature. Practically speaking, the electron’s spin is measured by placing it in an external magnetic field. The electron’s spin causes it to produce a magnetic field of its’ own. The electron will always either align its own magnetic field with the external field, or, it will be opposite to it. If opposite, the electron will emit a photon of light and flip to align, since this is a lower energy state (just like bar magnets will flip so that their magnetic fields align). This short video “Visualization of Quantum Physics” (2017) provides a graphic introduction to quantum mechanics, although it is talking about a particle moving freely in space, rather than the spin state of a particle.


Another strange aspect of quantum mechanics is entanglement. We can entangle electrons so that they become one
system of electrons. In such an entangled system, we can know all there is to know about the system without knowing anything about the individual state of a particle within the system (see a more detail description here). The system of electrons has literally become one
thing. Moreover, entanglement is the only phenomenon like this in all of physics, that is, it is the only means by which particles may become one system of particles larger than themselves. Furthermore, there is no theoretical limit on how many particles may be entangled together or how complex the system may be. Now, there are many ways to entangle electrons, but one way is to bring them close together so that they “measure” each other (so their magnetic coupling to one another is stronger than the coupling to the surrounding environment). When one electron measures the other, it will either find it spinning the same direction or opposite – just like any measurement must. The electron is not big enough to force a single outcome like we see when we open the toy box, so the two electrons will sit in a quantum superposition of states: they with both be spinning in the same direction and spinning opposite at the same time (we refer the reader back to this paper for a detailed mathematical description of what “big enough” is). They will remain entangled in a superposition until stronger external interactions, like with the environment or macroscopic observers, cause decoherence or specifically measure the system. Generally, in the laboratory, this happens very fast, like femtoseconds (one millionth of one billionth of a second) and is the reason most scientists are skeptical of quantum mechanics playing anything but a trivial role in biological systems. This paper, “The Importance of Quantum Decoherence in Brain Processes” by Max Tegmark (1999) shows, for example, that whole neurons are way too big to exist in a superposition of states for biologically relevant timescales due to decoherence. Still, there is abundant evidence that quantum superpositions and entanglement exist in biological systems on smaller scales. A comprehensive list can be found in the nascent field of quantum biology for which the reader can find an excellent introduction in this book: “Life on the Edge: The Coming Age of Quantum Biology” by J. Al-Khalili and J. McFadden (2014). The best studied example of quantum effects in biology occurs in the process of photosynthesis in the FMO complex of green sulfur bacteria where quantum states are observed to persist for as long as picoseconds (one trillionth of a second) and which allows plants to convert light from the sun into chemical energy in a perfect, fast, 100% efficient process.

Decoherence rates are highly dependent on the surrounding environment and dynamics of the system. For example, if it is really, really cold (~ absolute zero), and isolated, then entanglement can theoretically last on the order of seconds or longer. The dynamics are critical too – like if something keeps cyclically pushing particles together – entanglement can, again, in theory, last much longer. If the cyclicality happens faster than decoherence, entanglement may, in theory, be sustained indefinitely. Interestingly, biomolecules in organisms are really buzzing, vibrating at frequencies ranging from nanoseconds to femtoseconds. Comparing these times to the picosecond decoherence times observed in photosynthesis and a plausible means by which quantum effects may persist in biological systems becomes apparent. The interested reader can find a mathematical description of this type of dynamic entanglement in these papers:

Persistent Dynamic Entanglement from Classical Motion: How Bio-Molecular Machines can Generate Nontrivial Quantum States” by G. G. Guerreschi, J. Cai, S. Popescu, and H.J. Briegel (2012)

Dynamic entanglement in oscillating molecules and potential biological implications” by J. Cai, S. Popescu, and H.J. Briegel (2010)

Generation and propagation of entanglement in driven coupled-qubit systems” by J. Li and G.S. Paraoanu (2010)

Steady-state entanglement in open and noisy quantum systems” by L. Hartmann, W. Dür, and H.J. Briegel (2005).

They describe a theory by which entanglement can be sustained in noisy, warm environments in which no static entanglement can survive. In other words, the way physicists try to build quantum computers today by completely shielding the qubits from the outside world probably won’t work in biological systems, but this isn’t the only way to go about it. This is an important point and is critical for the reconciliation we propose in this essay. We should note that this theory of dynamic entanglement has not been experimentally verified, but no one, so far, has done the experiments to look for it. For the rest of this essay, we will assume that this theory pans out experimentally and entanglement will be found to be sustainable in biological systems.


Now, suppose we entangle two electrons so that their spins are pointing parallel (see here for more about how this is accomplished in practice). We can place them in two separate boxes as shown in (figure 6). When we open any other door of the box, even if the boxes are at opposite ends of the galaxy, the electrons will be found to be spinning parallel to each other. The measurement of one instantaneously affects the state of the other no matter how far away it is. This is the property of quantum mechanics that Einstein labeled “spooky action at a distance”. Nonetheless, experiment after experiment has supported this strange property (see “Physicists address loophole in tests of Bell’s inequality using 600-year-old starlight“).


Figure 6: Two entangled electrons placed into two boxes through the top, separated by a galaxy, then opened on the side (or any side for that matter), will always be found spinning in the same direction -it could be either left or right, but A and B will always point the same way. Picture of Milky Way Galaxy here.


Once two electrons are entangled we can perform quantum operations on them to put the system into a superposition of four different states at once: (1) “A” up and “B” down, (2) “A” down and “B” up, (3) “A” up and “B” up, and (4) “A” down and “B” down. Entanglement is not limited to just electrons – photons (light), nuclei, molecules, many forms of quasiparticles including macroscopic collections of billions of particles can be entangled (see, for example, SQUIDs, phonons or solitons). To the extent these configurations have binary states (electrons: spin up or spin down, photons: right-handed or left-handed polarization, etc.) they may represent quantum bits or qubits like in a quantum computer (although analog quantum computing is just as plausible as a binary system). In the case of electrons, spin-up could represent a value of, say, “0” and spin-down a value of, say, “1”, to perform powerful quantum computations. The power of such computations is derived from the quantum computer’s ability to be in superposition of many states at once, equal to 2^n , where n is the number of qubits. So, the two-electron system can be in 2^2=4 states, but a system of eighty electrons could be in 2^{80} states at once – more states than there are atoms in the observable Universe. To imagine how this works, imagine a computer that produces a clone of itself with each tick of the CPU clock. For a 1-GHz clock speed (typical), every billionth of a second the computer doubles the number of states that it is in. So, after one nanosecond, we effectively have two computers working on the problem simultaneously. After two nanoseconds, four computers. After three nanoseconds, eight, etc. Entangled superpositions of this sort are the secret behind the legendary computing power of quantum computers (even though they barely exist yet! J).


However, to take advantage of all these superpositions, we must find a clever way to make them interfere with each other. We can’t look at the result until the very end of the computation and when we do the superposition will collapse. If we can get the states to interfere in the right way we can get the system to be in a superposition that is concentrated, with near 100% probability, in a state that corresponds to a solution to our problem. This is the case with a special algorithm known as Shor’s algorithm that can solve certain NP problems in polynomial time. NP problems are those that require exponential time on a classical computer to solve (see more on P vs NP here, and here). Shor’s algorithm uses something called the quantum Fourier transform to achieve this speed-up and is used to factor large integers. This is an important problem in cryptography and is the “go to” technique that encrypts substantially all the traffic over the internet. For example, factoring a 500-digit integer will take longer than the age of the Universe on a classical computer, but less than two seconds on a quantum computer – hat tip to John Preskill for the stats, see his great introductory video lecture on quantum computing here (2016). To perform such computations, it is thought to require about 1,000 qubits. Other examples of NP problems include the infamous traveling salesman problem. It is an open problem whether all NP problems can be solved in polynomial time on a quantum computer. The vast majority of physicists and computer scientists think this is unlikely, however.

It is time to note, though, that there is a strange, unproven, powerful possibility lurking in quantum mechanics. All the quantum computers that have been designed to date utilize something called the Linear Schrödinger Equation (LSE) – an ubiquitous form in quantum mechanics. That means that the qubits are contained by forces external to the qubit system itself, like an external magnetic field. A much rarer, and controversial, situation in quantum physics involves the Non-Linear Schrödinger Equation (NLSE) and this occurs only when the quantum state wave functions interact with themselves. NLSE systems may potentially have a profound impact on quantum computation because they can theoretically solve NP-complete problems in polynomial time (only if the time evolution of the Schrödinger equation turns out to be nonlinear), and this means they can solve all NP problems in polynomial time. The interested reader can dive in here: “Nonlinear Quantum Mechanics Implies Polynomial-Time Solution for NP-Complete and #P Problems” by D. Abrams, S. Lloyd (1998), and in chapter 5 here “NP-Complete Problems and Physical Reality” by S. Aaronson (2005). So far, such a system has never been implemented, nor even a theoretical design proven though the idea continues to be debated. Here is the latest on the subject: “Nonlinear Optical Quantum-Computing Scheme Makes a Comeback” by D. Brod and J. Combes (2016).


The NLSE does appear in the study of a number of special physical systems, , for example, in Bose-Einstein condensates (BEC) (see this paper on building a quantum transistor using the NLSE in a BEC), in fiber optic systems, and also, especially interestingly, in biology: like the Davydov Alpha-Helix Soliton which forms a complex quasiparticle that transports energy up and down the chain of protein molecules, and in Fröhlich condensates which have recently been observed experimentally in biomolecules upon exposure to THz radiation (see Lundholm, et al. 2015). The interested reader can dive into Weinberg’s original paper (1989) on the NLS Equations here for more, and further enhancements of the theory here and here that address some difficulties. Also, see here for the development of the NLSE using Ricati equations.

IV. The Origin of Choice and the First/Third Person Duality

Getting back to free will, a natural first question is then: when and how does the 1st person perspective arise? We know we have it, but at what level does this perspective emerge? Does a single particle have it? An atom? A molecule? A large configuration of molecules? Only a certain configuration of molecules? A cell? Only a special configuration of cells? All of these seem somewhat arbitrary and it feels implausible to suggest that the 1st person perspective is not present in any level of matter until the final, critical particle or molecule is added, and then, suddenly, a whole new 1st person perspective emerges. There are formal arguments against free will as an emergent phenomenon from the field of philosophy detailed here, for example, supervenience, but these don’t seem any less baffling than emergence itself. Besides, sleep can be induced in humans with certain anesthetics, radically altering their 1st person experience temporarily. This suggests that whatever does give rise to the 1st person perspective, it is dynamic, transitory, and depends on the environment. So, where to start?


This paper, “The Strong Free Will Theorem” by S. Conway and S. Kochen (2008), describes a rigorous theorem of physics called the free will theorem, the meaning of which the authors summarize as follows: “if people have free will then so must elementary particles”. Perhaps a more precise description of the results of this paper is that if people’s actions are not determined solely by their histories than elementary particles are indeterminant as well. Scott Aaronson in “The Ghost in the Turing Machine” (2013) describes the theorem more cynically: “for the indeterminism that’s relevant here is ‘only’ probabilistic: indeed, (people and elementary particles) could be replaced by simple dice-throwing or quantum-state-measuring automata without affecting the theorem at all”. Suffice it to say, we won’t dwell on the arguments of the theorem here (if you’d like to dive deeper check out this video here, or this talk by S. Conway here). Instead, elementary particles, like the electron, seem like as good a starting place as any. After all, they are the most fundamental things in the Universe, and, therefore, feel like a less arbitrary place to start. So, we’ll jump on Freeman Dyson’s bandwagon (opening quotation) and run with it and see where it takes us…


In 1922, in the Stern-Gerlach experiment, silver atoms were fired through a magnetic field as depicted in (figure 9). The magnetic field deflected the atoms upward or downward depending on the direction the silver atoms were spinning. Classical physics expected a continuous distribution on a detector on the far side of the apparatus (see -4- in figure 9) because the silver atoms could be spinning in any direction. The distribution that was actually seen was two singular points (see -5- in figure 9) proving that the silver atom’s spin was quantized. We’ve already said that the electron’s spin is quantized and if we perform this experiment on electrons instead of silver atoms we will see the same result – all the electrons will end up at one of two spots depending on whether their spin is pointing up or down. Just like in our toy box metaphor, this Stern-Gerlach apparatus is one way of measuring the spin of the electron. Now, physicists know exactly how to calculate the quantum mechanics of this problem and it says we will see the electron end up at the upper point with fifty percent probability, and at the lower point with fifty percent probability. But, that is all it will say. There is no way to know more about the electron’s spin than this probability – there is no way to predict it. It is truly random.

So, now, let’s just suppose the 1st person perspective is present in the electron and it does make a choice. From the electron’s perspective, it feels the quantum probability distribution manifest as a matter of preference. In this case, since the quantum probabilities are equal, it is indifferent, it prefers both choices equally and so it selects one with equal probability. To the physicist, the electron follows the laws of quantum mechanics exactly, the wave function collapses to one of two outcomes that are equally probable as given by the rules of quantum mechanics. Both the 3rd person and 1st person descriptions of the event are present, valid, and equivalent – as, obviously, they must be if we are going to claim the electron has a 1st person perspective dual to quantum mechanics. Now, notice that we forced this choice (measurement) upon the electron. It did not have any say in the matter, we just fired it through the Stern-Gerlach apparatus. Nor does it have any memory of the measurement afterward. After our experiment, the electron goes on its merry way constantly being measured, forced to make choices by the surrounding environment, and having no means to retain a memory of those choices nor any future anticipation of choices to come. No past, no future, just moments of “now”. No understanding, no self-awareness, no consciousness as we know it, just repetitive, uncontrollable, forced choice. Practically speaking, we are talking about roughly nanoseconds before an average electron interacts with something again and is measured – these moments are very brief and fleeting indeed. In a subsequent section, we will explore in more detail what it is like to be an electron.


There is nothing magical about a fifty-fifty proposition by the way. The electron could have been prepared, prior to entering the Stern-Gerlach apparatus, in a superposition of 90% up and 10% down, or 70% down and 30% up, etc. Quantum mechanics predicts the outcome for the 3rd person view precisely, as given by the skewed wave function, and the electron, in the 1st person, experiences the higher probability choice as feeling more compelling – like ice cream versus spinach – and chooses accordingly. Measurement is still random in 3rd person and free choice in the 1st. Measurement and choice are dual to each other. Dual descriptions of the same thing.

Figure 10: A single electron fired through a Stern-Gerlach apparatus. Electrons enter the apparatus moving right to left in a quantum superposition of states – each electron is both spin “up” and spin “down”. The electrons interact with the magnetic field of the Stern-Gerlach apparatus and are projected onto a detector. Those with spin “up” end up at point “A”, with spin “down”, at point “B”. The electron remains in a superposition of “up” and “down” all the way up until measurement at “A” or “B”.

Now, what happens if we run this experiment with a system of 3 entangled electrons connected in some way (a 3 electron chain) as shown in (figure 11)? Several things change in very interesting ways (we ignore the technical details and practical challenges in doing this for now). First, there are four possible outcomes instead of just two: (1) we can have all 3 spins pointing up, (2) two spins up and one spin down, (3) two spins down and one spin up, or (4) all three spins pointing down. Incidentally, states (1) and (4) form something known in quantum computing as a GHZ state (Greenberger-Horne-Zeilinger state). Also, note there are three different combinations of forming state (2) and state (3), but just one way to form states (1) and (4). Second, the system may exist in a superposition of up to eight different states at once, 2^3=8 , so our little electron system is beginning to hint of a basic quantum computer. Third, even after measurement, unless all the spins are pointing up (point A in figure 11) or all the spins are down (point D in figure 11), the system is still left in a superposition of states. There are three different states it could be in assuming it ended up at point B (figure 11), and three different states it could be in if it ended up at point C (figure 11). Measurement does not destroy the system. It reduces the superposition, certainly, but the entanglement persists. Fourth, if the electrons end up at B or C (in figure 11), the superposition retains something that could serve as elementary memory: all the remaining three states have a symmetry to them – the sum of their spins is +1/2 (at B), or -1/2 (at C). If the system is subjected to the same measurement again, it will end up at the same spot – a memory of the prior measurement results is stored in the superposition. The system is in an eigenstate of the measurement with eigenvalue +1/2 (at B), or -1/2 (at C). For example, looking at (figure 11), all three states of the electron system, if it ends up at B, have two spins up and one spin down. Each spin up is +1/2, each down spin is -1/2, so the sum for each state is +1/2 (e.g.+ ½ + ½ – ½). Last, because we measured an aggregate property (its total spin) of the system, the entanglement is not broken – it remains one system and can be measured again. We will come back to how this quantum memory can then be converted into a more permanent memory in subsequent sections. Other properties of the system can, in some cases, be measured too, without disrupting the system. This can happen if, in quantum-speak, the measurement operators commute (the interested reader can dive deeper into quantum operators here). For example, we can measure the momentum of an electron along the x-axis without disrupting the momentum along the y-axis. Different directions of spin can’t be measured simultaneously, however, but, some quasiparticles, which we will come to later, have infinitely many conserved quantities and can therefore be measured in infinitely many ways.


In the 1st person the entangled system chose from four different subjective preferences, say ice cream, pretzels, brussels sprouts, or spinach. Some choices may be more likely than others with the electron’s subjective preference for each equal to the quantum probability of that outcome. A rudimentary memory persists of its choices. If subjected to the same choices again, the answer will be the same. And, the system’s identity as one thing persists beyond making a choice – it lives to choose again! J



Figure 11: Chain of three entangled electrons represented as
(e^-)(e^-)(e^-) are fired through the Stern-Gerlach apparatus. (3rd person description): The 3-electron-system going into the apparatus may be in a superposition of eight states simultaneously. The magnetic field will deflect the electrons where they will be detected (measured) at one of four locations, labeled A, B, C, or D, depending on the spin state. The probability the electron-system is in each state is given by a coefficient \alpha_k , where sum \alpha_k^2 = 1. States with greater net spins are deflected more severely. If deflected to locations C or B, the electrons still persist in a superposition, albeit a reduced one. In any case the system remains entangled. (1st person description): The 3-electron-system must make a choice upon traveling through the apparatus. The appeal of each choice is equivalent to the quantum probability of finding the system in that state. The electron system after its choice retains a memory of that choice and its identity as “one thing” persists.


As the number of entangled electrons grows larger, say to 100, or 1000, suddenly our system takes on the appearance of a powerful quantum computer – it could be in 2^{100} or 2^{1000} different states simultaneously. The system of electrons still does not get to decide when to make a choice – we continue to force choice upon it by firing it through the apparatus, but the number of choices available to it, and the vastness of the superposition that can survive a choice increases substantially. For example, say a system of 100 electrons was found to have total spin of +1/2 up. There are ~10^{29} ways that 100 electrons, each having spin +1/2 or -1/2 can sum to a net spin of +1/2, so the system could still be in a superposition of this many states even after measurement. Also, the system could potentially choose from an array of 200 different possibilities (there are 200 different possible total spins). The degree of freedom of choice has increased substantially, although nothing resembling our free will yet, and a complex memory reflecting the results of those choices has emerged.




V. Crisscross Entanglement and the NonLinear Schrödinger Equation

Now, what happens if we have so many entangled electrons that the chain of particles crosses itself (as shown in figure 12)? That is to say, suppose the entanglement is sufficiently extensive that we no longer need the Stern-Gerlach apparatus. The tail of the chain of entangled particles (labeled “B” in figure 12) can effectively serve as the macroscopic magnet in the Stern-Gerlach apparatus while the front (labeled “A” in figure 12) acts as our chain of electrons passing through. Some especially interesting things now begin to happen.



Figure 12: System of entangled electrons that crosses itself. The region of the entangled chain near end “B” acts like the Stern-Gerlach magnetic field, and the electrons near end “A” play the traditional role of spinning particles in the experiment. The entire chain is one entangled system so it can simultaneously be in states forming various virtual Stern-Gerlach apparatuses as well as different system states. For example, if all the electron spins near end “B” are aligned pointing up, the magnetic field will be pointing up as in a traditional Stern-Gerlach apparatus. However, if the electron spins near end “B” are an even mixture of up and down spins then no Stern-Gerlach magnetic field would be present and the electron chain at end “A” would pass straight on through.


In the 3rd person quantum description the whole chain is entangled as one system and so will be described by a single wave function. We can expect all the features of the three-electron case, elucidated earlier, to still hold – such as robust quantum computing power, a potentially vast superposition of states, and a means to store the results of measurements in a form of memory while still maintaining entanglement – but, additionally, a complex non-linearity now emerges. The wave function interacts with itself. That is, the end of the entangled chain at “A” (in figure 12) will interact with a magnetic field induced by the chain at end “B” (in figure 12). This means that an NLSE is created, and, if the time dependence, too, is nonlinear, then the system is not functioning merely as a typically quantum computer, but, potentially has the power to solve any NP problem in polynomial time.


The system, in general, may exist in a vast superposition of states, but two broad categories of states are of special interest for characterizing the system. First, those states where substantially all the electrons near end “B” have spin up, and second, those states where the electron spins near end “B” are evenly mixed up and down. In the former case, illustrated in (figure 13 – top), the electron chain at end “A” experiences a magnetic field generated by end “B” similar to the external magnetic field of the Stern-Gerlach apparatus. With the magnetic field turned “on” in this case, the beam at end “A” is split depending on its spin state. In the latter case, illustrated in (figure 13 – bottom), the electron chain at end “A” experiences no magnetic field because the electron spins at end “B” mostly cancel each other out. The chain at end “A” is not split because the magnetic field is effectively turned “off”. Each state has a coefficient, \alpha_k , and so the likelihood that the system will have the magnetic field turned “on”, as in the first category, will be related to the aggregate probability associated with these coefficients, and, likewise, for the latter category with the field “off”. Beyond these two categories there are other interesting states the system could be in – for instance with substantially all spins pointing down, effectively creating an inverted Stern-Gerlach apparatus. We merely call out these two as being illustrative of the fact that measurement of this system reveals a complex nonlinear dependence on itself. Measurement of the system does not mean just measuring the state of the electron spins near end “A”, it means measuring whether the system induced a magnetic field or not as well.


Figure 13: Two broad categories of the electron system are remarkable. (Top) The category of states that have substantially all of the spins at end B pointing up – more or less replicating the magnetic field of the Stern-Gerlach apparatus, and (bottom) the category of states that have end B in a roughly evenly mixed distribution of spins up and down – effectively producing no net magnetic field.


Especially interesting, however, is the 1st person perspective: the system no longer has choice forced upon it like the prior cases we’ve examined. In this configuration, the system can choose whether to subject itself to making a choice or not. That is, by choosing the state of the electrons near end “B”, the system is choosing whether to use a Stern-Gerlach-like magnetic field to split itself at end “A”. Something resembling real free will has emerged: the ability not just to make a choice, but to choose what choices to make, and, even, whether to make a choice at all! To the system, each state in its quantum superposition feels preferable in relation to the \alpha_k coefficient of that state. The system prefers to turn “on” the magnetic field and “think” about some choice in direct relation to the aggregate \alpha_k coefficients that apply to the “all spins up” category of states as shown in (figure 13 – top). Similarly, the system prefers to ignore “thinking” about a particular choice in relation to the aggregate \alpha_k that correspond to the “spins evenly mixed” category of states as shown in (figure 13 – bottom). The system at once follows the laws of quantum mechanics, and has the freedom to choose what choices to make at the same time.

VI. The Mind’s Eye and Free Will

So, what does this have to do with our feeling of free will? Suppose that you are such a collection of entangled particles existing throughout your brain, nervous system, or perhaps every cell in your body. We’ve already discussed the challenges of maintaining quantum entanglement in such an environment, but, there is a way, in theory. Entangled systems become “One” system in the 3rd-person quantum description and this manifests as your feeling of being “One” entity in your 1st person experience. Measurement in 3rd person is choice in the 1st, while the eigenstates that result from measurement/choice manifest as memories in the 1st. The crisscross entanglement generates a nonlinear Schrödinger equation in the 3rd person quantum description, and manifests in the 1st person as your “mind’s eye“. This is how you focus your thoughts – how you control where you project your attention. When you focus your mind on something, and direct your thoughts, this is like the part of you near end “B” focusing yourself at end “A”. It could be you choosing to focus onto life choices, onto the possible actions you may take, onto the subject matter you wish to think about, or on sensations you want to detect, for example.

Quantum probabilities always manifest themselves to you as preferences. You are more likely to direct your thoughts to those states with higher \alpha_k state coefficients, that is, you are more likely to direct your thoughts to those things you prefer. You freely choose what to think about. And, once you’ve chosen where to direct your thoughts, the choices you make there, too, follow quantum probabilities corresponding to your preferences. So, your will is free and indeterminant, but it is constrained to follow the probabilities of quantum mechanics – you are constrained to probably do what you want and need to do.

Is this truly free will, though? Descartes famously said: “the will is by its nature so free that it can never be constrained“. But, if we examine our will certain things are very hard to do. For example, it would be very hard to, on a whim, stab ourselves in the gut with a knife. Search your feelings, do you think you can even will yourself to do that? I have a very strong preference to not do this action. The quantum coefficients there are very small. Even though my will is free it is probabilistically constrained. On the less dramatic side, I have a very hard time resisting chocolate. My best strategy is to not even think about eating chocolate. I have made this mistake in the past and felt terrible later. I have learned over time, and, relying on my ability to store long-term memories, my quantum probabilities have adjusted to avoid this trap. Nowadays, I am aware of the consequences of my choices, my preferences have adjusted, and I don’t “go there”. This illustrates how our preferences can be recursively affected. Furthermore, the more I think about chocolate the more tempting it becomes – the mere act of thinking about something can recursively alter the state we are in, change our preferences. The quantum state coefficients may be altered the more and more we think about something. And, once I eat one bite, it becomes almost impossible to not eat more. My choices feel constrained probabilistically to my preferences which are dual to the quantum state coefficients.

Figure 14: Artist’s illustration of the mind’s eye. The focus of our thoughts can feel like a third eye. From Psychology Today here.

Let’s consider a Gedänken experiment in free will. Think about whether you would like to go out to dinner tonight. Let’s suppose in your brain somewhere there is a “button” that, if pressed, will set in motion a chain of events that will lead to going out to dinner. We will defer the discussion of the physical nature of this button until the subsequent section. For now, just suppose it exists. Last, let’s suppose that you feel 50%/50% about it – you are on the fence and could go one way or the other with no clear preference. In your brain, you are using your mind’s eye to think about and explore the idea – focusing your thoughts on this button. This consideration is crudely like you using end “B” to focus end “A” on that button to measure yourself. This is called a weak measurement in quantum mechanics. You make an inconclusive measurement that gives only partial information about the state of the system. It leaves you open to many possibilities without committing to one. Many weak measurements will give you an idea of the quantum probabilities. If you feel 50%/50% it means that the projection of yourself onto that “go-out-to-dinner” button has an aggregate quantum probability of 50%. That is to say, 50% of the probability-weighted states in the quantum superposition that makes up you, projected onto this button, have a value of, say, “1”, meaning go out to dinner, and 50% have a value of “0”, meaning stay at home. Of course, you can choose not to think about going for dinner, and the whole projection onto the button becomes irrelevant. Also, thinking about this choice and its consequences and ramifications can recursively affect the probabilities and alter your preferences too. You can definitely think about something so much you talk yourself out of it, “paralysis by analysis” as it were. Note, however, at the time you do make the decision, if you make it 100 times over, being that you are on the fence each time and under otherwise identical circumstances, you will freely choose to go out to dinner about 50 times – the results of your choices reconcile with the quantum probabilities. Also, we should say that this quantum system takes inputs from the outside world as well. For example, sensors that register sights and sounds as well as your own hunger level influence the state of the system. If you are very hungry, relevant sensors could strongly affect the system near end “B” skewing your preferences to strongly consider focusing on the problem of getting something to eat!

“You can choose a ready guide

In some celestial voice

If you choose not to decide

You still have made a choice

You can choose from phantom fears

And kindness that can kill

I will choose a path that’s clear

I will choose free will.”

– the song Free Will by Rush (1980)

Of course, thinking about the prospect of going to dinner, and actually doing it are two different things. If we make too many weak measurements too quickly we will ascertain the state of the system definitively and collapse the wave function – a strong measurement. If that’s what you want to do – if you choose to push the button – you focus on it sufficiently to activate it. You make enough weak measurements of yourself to reveal sufficient information about yourself to push the button, you make a definitive choice. You make a choice in the 1st person to push the button, and a measurement is made of you in the 3rd person by the button. Then, this button triggers a whole chain of events, including pressing other buttons, related to going out to dinner.

A great question naturally arises: can you “game” the system”? In other words, can you do what you don’t want to do? The mere act of thinking about this, however, changes the game. You no longer are just thinking about whether you want to go out for dinner, but are now considering a much more abstract topic. Indeed, you are projecting yourself now onto a whole different button – a “game the system” button!

VII. Making Sense of Experimental Results in Neuroscience

What about the experiments of Libet and others? How do we reconcile the deterministic, predictive experimental results of neuroscience with the indeterminant, crisscross quantum entanglement description of free will presented here? The short answer was provided by the experiments of J. Haynes, B. Blankertz and M. Schultze-Kraft who had patients play a game against a computer interfaced to read their EEG activity real-time, “Point of No Return in Vetoing Self-Initiated Movements” (2015). Contrary to the conclusion of Libet and others, the team showed that you can still willfully override the RP and outdo prediction by the computer up to a point of no return just prior to action. This suggests that something besides the neurons is functioning here, affirming (although not proving) the argument for free will, because you can consciously veto or cancel an action after prediction by an RP (visit the group’s website here to learn more). However, this does nothing to describe how the crisscross quantum entangled system we have described here could exist in an organism, nor how it interacts with neurons, RP’s, the brain and the rest of the organism. And, frankly, this is a very complex question which we will not resolve here. Rather, our purpose is to describe, at a high-level, a plausible mechanism by which this might happen. Probably, this does not involve simple particles like the electrons we have described, but more likely complex quasiparticles (e.g. the Davydov Soliton – see figure 8). We think this will provide a sliver of insight for future, more detailed, investigations and compelling circumstantial arguments for free will now. Next, we will review some existing theories regarding quantum effects in the brain, what the buttons and sensors we talked about above might be, and how the quantum systems we described might interact with them and reconcile to experimental results.


We have already seen that neurons themselves are too big to persist quantum entanglement (see “The Importance of Quantum Decoherence in Brain Processes” by M. Tegmark (1999)), but scientists have suggested other theories involving much smaller mechanisms that may support quantum entangled states in the brain. One theory involves ion channels (see “Ion Channels: Structure and Function“). These channels allow sodium, calcium, potassium or chloride ions to flow into and out of neuron cells throughout the nervous system. They are only about the diameter of a single ion, even though millions of ions per second pass through them, and regulate very precisely the ratio of sodium to potassium ions they allow through. The ion channels are small enough they are susceptible to quantum effects, but can still influence neuron firing suggesting a conceivable way that quantum effects could be magnified and thereby manifested at a macroscopic level (a button press!). The process of thinking about something, exploring our preferences, could affect these ion channels through weak measurement and result, through amplification, in increased neuron firing rates and cause the formation of the readiness potential (RP) witnessed by Libet prior to motor activation. See, for example, this paper which shows how preference is related to the RP: “The LRP (lateralized readiness potential) is capable of measuring preparatory motor activity underlying the dynamic accumulation of subjective preference in the premotor cortex” (2014). A choice, or button press, occurs when ion channels are affected even more significantly and increase neuron firing rates enough to initiate action. In this paper “The Speed of Free Will” by T. Horowitz, J. Wolfe et. al. (2009), the authors compare the time required for voluntary shifts of attention versus task-driven shifts (i.e. external stimulus). The voluntary shifts occur more slowly suggesting a speed of free will on the order of 100-200 milliseconds. This is consistent with the framework we describe and indicates the time latency for quantum effects to be amplified. Still, the quantum entangled system discussed here would require a vast network of ion channels to all be entangled. How could ion channels in different neurons – vast distances for quantum entanglement – be entangled together?


In quantum networking, if we have a photon source that produces entangled photons (an EPR source) and we send one photon to lab A and another to lab B and then let them interact with qubits in those labs we can entangle the qubits at A with the qubits at B without them ever coming into contact with one another. Even if labs A and B are far apart (many kilometers apart). After the photons interact with the qubits the photons can be measured, discarded, or whatever – the entanglement between the qubits will remain. We know biological decoherence rates are very fast, like picosecond-fast, but if continual absorption of entangled photons from an EPR source by the ion channels cyclically reestablishes entanglement ala’ a biological quantum network, it could allow entanglement to persist. Since biomolecules, such as DNA, can absorb, down convert, and reemit photons on time scales ranging from picoseconds to femtoseconds they may be a possible EPR source (see here for details on internal conversion). Photons that interact with the vibrational frequencies of biomolecules, such as THz, are candidates (see “Observation of coherent delocalized phonon-like modes in DNA under physiological conditions” by M. González-Jiménez et. al. (2016)).


Figure 15: A diagram of a quantum network from Centre for Quantum Computation & Communication Technology. EPR sources at either end are sources of entangled qubits where A&B and C&D are entangled. The joint measurement of B & C occurs at the quantum repeater in the middle entangling A & D at a distance.



There has been much study of the electromagnetic field (photons) of the brain (the EM field) – these “brain waves” are what we see in EEG readouts like Libet’s. The source of this field has never been understood, however. There are many theories that relate the brain’s EM field to consciousness, for example the CEMI (Conscious ElectroMagnetic Information) theory. In this theory, the EM field interacts with the ion channels to synchronize neuron firings, but the neuron firings produce changing electric and magnetic fields and therefore reciprocally affect the EM field. Another interesting theory of quantum effects in the brain has been proposed by S. Hameroff and R. Penrose in their Orch-OR (Orchestrated Objective Reduction) theory of consciousness. In this theory, tiny microtubules, which form the cytoskeleton of all cells in the body, but are particularly prevalent in neurons (~ 10^9 per neuron), support quantum entanglement. Microtubules have been shown in the laboratory to support certain kinds of quantum states known as topological qubits (see for example: “Discovery of quantum vibrations in ‘microtubules’ corroborates theory of consciousness“). Microtubules in one cell are theorized to communicate with microtubules in neighboring cells through gap junctions although quantum effects across junctions have not been experimentally verified. Perhaps a mechanism involving an EPR photon source is involved here as well, for example, photon-quasiparticle interaction between neighboring microtubules. Decoherence times in microtubules, like ion channels, also tend to be on the order of picoseconds which, again, is long enough that entanglement could be sustained if it were being cyclically refreshed at rates faster than that. Especially implicating is experimental evidence suggesting that anesthetics, known to cause patients to sleep and lose consciousness, chemically bind to sites along the microtubules (see for instance “Quantum Criticality in Life’s Proteins” (2015)). Also, evolutionarily, single celled paramecium have been shown to exhibit learning capability even though these organisms are too simple to have neurons or a nervous system. They do, however, have a network of millions of microtubules comprising their cytoskeleton. Interestingly, ion channels, microtubules, and the Davydov alpha-helix all involve a biomolecular helical structure (as do many proteins and DNA itself) which can give rise to nonlinear quantum interactions and, therefore, quasiparticles such as the Davydov soliton. For instance, the quantum mechanism may involve lateral molecular oscillations (e.g. in hydrogen bonds) entangled with longitudinal phonons to generate a NLSE whose solutions are described by a propagating quasiparticle. Lastly, we should say that it may be that not one but all of the above mechanisms, and others, collectively form some complex NLSE satisfying quasiparticle that collectively gives rise to the mind’s eye.


This is not without precedent in Biology as the mechanism that transports energy to the reaction center in photosynthesis is proven to be another quasiparticle known as an exciton (an electron-hole pair). Solitons are “propagating pulses or solitary waves that maintain their shape and can pass through one another” (from here). Think of a chain of rogue waves for intuition. Such a system means that no individual electrons are necessarily moving throughout the brain like in a classical electrical system, but rather a composite quasiparticle comprised quantum mechanically of a collective wave function of entangled particles. Other examples of these quasiparticle systems include Cooper pairs in superconductors, magnons (quanta of spin waves), polarons, and phonons (which are known to propagate up and down the double-helix of DNA and thought to direct the replication of DNA in what is known as a transcription bubble). There are all kinds of quasiparticles, a list is here.

Figure 16: Image of the alpha-helix structure ubiquitous in biological systems. Helical structures give rise to nonlinear Hamiltonians
which, in turn, imply the Nonlinear Schrödinger equation. This has quasiparticle solutions – like the Davydov soliton that transports energy along the alpha-helix. The nonlinear Hamiltonian arises from transverse quantum states entangling with longitudinal phonon states. This nonlinearity of entangled particles (in the 3rd person description) is dual to the mind’s eye (in the 1st person, subjective description). This image is from here, image from Voet, Voet & Pratt 2013, Figure 6.7


So, we have an entangled quasiparticle system in the 3rd person that is dual to our feeling of being One in the 1st person, and, moreover, the quantum entangled system interacts with the outside world by pushing buttons and being affected by sensors. The buttons could be neurons via amplification of quantum effects. Sensors, too, could be neurons affecting the quantum system, or something much smaller like the ion channels. To make our bodies do anything or say anything, we need to push these buttons – just like Buddhist scholar Alan Wallace says “the brain is the keyboard of the mind“. Libet’s experiments are measuring the action of the neurons, and the neurons are your keyboard and a critical resource for your mind, but you are not those neurons. And so, when these experiments are conducted they are measuring you through the different ways you interact with the outside world, by pushing the “speak” buttons or the “finger press” buttons. The timing differences these experiments measure are just the timing differences between button presses. These experiments are measuring events correlated with each other in the cascade of neuron firings that produces action, but these events are not the original cause. The reporting of “conscious choice” by subjects is, itself, the reporting of a button press – the button to report the choice. Only when you sufficiently focus your quantum self to fire that neuron(s) does the button get pressed. Only then does a full choice/measurement occur. The decision to override the RP is yet another button press – the negation of the “finger press” button. All deliberate actions start with a button press, but, the original cause originates from your free will, from your mind’s eye, from the crisscross of a quantum entangled system.




There is evidence in Psychology that there are two types of memory used by the brain: short-term memory and long-term memory. Short-term memory typically lasts for something on the order of about 18 to 30 seconds, while long-term memory lasts much longer – potentially for the life of the organism. The evidence for these two distinct kinds of memory is based on case studies of patients with a disease called anterograde amnesia as well as certain kinds of “distraction tasks” that seem to affect one or the other types of memory in isolation. Patients with anterograde amnesia tend to have working short-term memories but have difficulty forming long-term ones. In other words, they can retain memories for 30 seconds or so. Such a description of memory naturally fits in with the quantum entangled system we have described above. In such a system, short-term memory is that information which is encoded by collapsing the superposition to an eigenstate of the measurement operation with the chosen/measured eigenvalue – like we described in the 3-electron case above. So, you start in a superposition of states, you choose to think about where to go out for dinner. That choice leaves end “B” in an eigenstate, say, with all the spins pointing up focusing you onto the choice of where to go for dinner. Upon thinking about it, you decide, say, to go to restaurant XYZ. There again, that choice leaves you in an eigenstate – this time at end “A”. So that all states at end “A” have total spin equal to, say, +7/2, which corresponds to restaurant XYZ. Every time you make a choice, you are subjecting yourself to measurement and collapsing your state to an eigenstate of that measurement. You might still be, and probably are, in a vast superposition of states, but all the states have a symmetry to them – an aggregate property of each state, like the total spin, is the same. That is short-term memory, but quantum states are difficult to preserve, even with redundancy and error-correction, so an organism needs to encode this memory in something more stable, more macroscopic. This is where the neurons and long-term memory come in. But, how is this information transferred to long-term memory?


The Hebbian theory of neurons tells us that “neurons that fire together wire together”. Our quantum entangled system, when run through the same measurement conditions repetitively would realize the same outcome over and over. And, if that outcome is amplified to induce neuron firings, then it could cause the same neurons to fire over and over. That is because the quantum superposition is still in an eigenstate. Once a choice/measurement is made, if the same measurement is repeated the system will produce the same result. This may be the feeling of having “your mind set on something” or “your mind made up”. In other words, if the magnetic field generated by end “B” is unchanged and we pass end “A” through it again and again, it will wind up projected onto the same place. For example, if all states of the system have the symmetry that their net spin is +3/2 at end “A” then this will be indicated by their trajectory upon exposure to the same magnetic field from end “B”. The chain of entangled particles will be focused to the same place. Iterated through a loop a number of times, like a broken record playing over and over again, would produce the repetitive firing of the same neurons which then would cause those neurons to wire together – forming a long-term memory of that choice. If you have ever had the experience of, when trying to remember something, you keep “saying it” over and over in your mind, this is possibly the dual description of that experience. You use your mind’s eye to keep playing it repeatedly until it sticks – until the neurons “wire together” per Hebbian principles. Such a model is consistent with the results described in this paper “Delaying Interference Enhances Memory Consolidation in Amnesic Patients” by M. Dewar et. al. (2010), where, if there were no distractions, even patients with amnesia could continually keep the short-term memory “in mind” and give it the extra time needed to wire the neurons together for long-term memory.


So, imagine our quasiparticle system is a system of “brain solitons” propagating around the brain, like a “ticker-tape” of information entangled as One system. Perhaps following a general path like that shown in (figure 17). Inducing the appropriate neurons to fire in synchrony, over and over again, and wire together. One system of particles entangled together but no individual particle is the system. In fact, individual particles may be added, replaced or exchanged over time which is consistent with isotope studies that show that the vast majority of atoms in the body are recycled over time. The critical difference between the ticker-tape of the mind and a classical ticker-tape is that it can be in a vast superposition of states at once. Like zillions of classical ticker-tapes flowing at once and directed by the mind’s eye. All of this is at once described by this quantum mechanically in the 3rd person description, and in the 1st person as what it is like to be you! A mind’s eye, a short-term quantum memory, quantum computing power to enable creative leaps and “aha!” moments, long-term memory storage via neurons – a full-on conscious experience is emerging! However, we must say, as interesting as this depiction is, it clearly is an over-simplification of a very complex process of making choices and storing memory in the brain, and we will not pretend to have all the answers here.


Figure 17: Flow of quantum information as a quantum “ticker-tape: in the brain takes the form of a propagating quasi-particle. Such a quasiparticle could take the form of a “brain-soliton” resulting from a nonlinear Schrödinger equation – the mind’s eye. Communication between the hemisphere’s may take place through the corpus callosum and explain why split-brain patients (who have it severed) exhibit traits of two wills. Brain picture from public domain pics here.


In this article “The Great Cerebral Commissure” (1964) by Nobel Laureate R. Sperry, the author talks about “split brains” and their effect on brain functioning. Specifically, the corpus callosum is a massive structure of nerve fibers that connects the two halves of the cerebral cortex. In some cases when patients suffer from epileptic seizures, surgical procedures have been performed to cut the corpus callosum forming split brains. This was effective at halting the seizures, and, at first it appeared as though patients recovered completely from this procedure with no ill-effects. This caused many physicians to wonder what was the purpose of the corpus callosum. Later, Sperry’s experiments on animals took a deeper dive and showed that “it was as though each hemisphere were a separate mental domain operating with complete disregard – indeed, with a complete lack of awareness – of what went on in the other”. This lead Sperry and colleagues to conclude that the “corpus callosum has the important function of allowing the two hemispheres to share learning and memory”. In humans, what seems to happen is one of the hemispheres turns out to be dominant and takes control of the person’s functioning. Tests that isolate the hemispheres show: “(upon) discussing such responses afterward, the patient typically has no recollection of having pointed with his left hand; the dominant hemisphere seems completely ignorant of what went on in the other one.” Sperry went on to say, in regard to experiments on monkeys, “one hemisphere or the other takes command and governs the monkey’s behavior. This dominance may shift from time to time, each hemisphere taking its turn at control, but it would appear that no serious conflict disrupts any given movement.” Perhaps Sperry’s split brain research suggests a flow of brain solitons we described above in (figure 17) in a healthy brain. When the corpus callosum is cut, however, the flow of short-term memories in the quantum ticket-tape between the two halves is disrupted as shown in (figure 18). The patient recovers, but the new topological flow of solitons shifts to the dominant half only. In this article “The split brain: A tale of two halves” by D. Wolman (2012) the author says “the brain isn’t like a computer, with specific sections of hardware charged with specific tasks. It’s more like a network of computers connected by very big, busy broadband cables. The connectivity between active brain regions is turning out to be just as important, if not more so, than the operation of the distinct parts.” The quantum entangled self, the ticker-tape, is, perhaps, the “broadband connection” unifying the brain’s regions. Neurons in the non-dominant half still function and can perform tasks, but the mind’s eye, and the Oneness of the organism persists only in the dominant half. You may have felt a small fraction of this effect, for example, if you ever had the experience of aiming a bow & arrow. While both eyes are passing visual information to your brain, your mind sees and aims subconsciously only with your dominant eye.


Figure 18: Possible flow of the quantum “ticker-tape” of information, “brain solitons”, after patients have their corpus callosum severed. R. Sperry observed that one half at a time becomes dominant, takes control of the mind, and carries on unaware of the actions undertaken by the other half of the brain.


You can get a better feel for the relationship between the quantum entangled mind’s eye and the functioning of neurons by examining vividly the common everyday experience of driving an automobile. You’ve probably had the experience where, while driving, your mind drifted onto something else. Your brain still steers the car, and operates the gas and brake as if on auto-pilot (this phenomenon is so widespread the phrase “highway hypnosis” has been coined). Usually it does so reasonably well. When operating in this mode, depending how deep in thought you are, you might drive right past an important exit without even noticing. All the visual images still fire the same neurons in the visual cortex, it’s just that without your focus nothing is done with that information. The quantum brain-soliton ticker tape doesn’t take that information where it needs to go to initiate action unless you are focusing it there! On the other hand, if you encounter something out of the ordinary that sets off a “red alert”, such as an accident, construction, or your co-pilot says “you missed our exit!”, then suddenly your mind’s eye is called to attention. These “alert sensors” could be neurons that can affect the state of yourself at end “B” causing end “A” to be focused on the present situation requiring attention. The two-way relationship between your macroscopic self, the neurons, and your quantum self is illustrated well in this situation.


Another illustrative example you may have encountered is the experience of looking at an image, and, for a few seconds, you have no idea what you are looking at. It may mean the neurons by themselves aren’t able to recognize the image. It seems the mind’s eye has to get involved somehow to recognize the image – to adjust the timing of neuron firings, to bus the information on the ticker tape to other regions of the brain, or place them in context to achieve recognition. This is called “top-down reasoning“. When humans only have a split second to look at an image and do not have time to invoke top-down reasoning, they can recognize images only about on par with the best machine learning models. These machine learning models, interestingly, use so-called deep learning neural nets which use a neural network structure patterned after the structure of neurons in the visual cortex. However, on hard images that don’t offer instantaneous recognition, humans, if allowed time to think about, can use top-down reasoning to recognize images better than machines. This is the basis for modern “CAPTCHA’s” – Completely Automated Public Turing test to tell Computers and Humans Apart. No computer machine learning models have such functioning, and so far, it has not been understood what is involved to produce it. Also, it is an unsolved question how the brain came up with the neurological structure of the visual cortex, especially since the problem of finding the right structure seems to involve a highly non-linear problem (e.g. discovery of “max pooling” configurations). Quite possibly, in early development, it is the quantum entangled aspects of the organism that are engaging to solve such difficult, probably NP, problems. Training methods in artificial neural networks that use gradient descent type approaches (i.e. non-quantum) tend to get stuck in local optima. But, invoking quantum computing power may provide an exponential speedup on learning problems of this kind and enable a global solution to be found (see this video “Quantum Machine Learning” which shows how quantum algorithms can be applied to neural networks by Seth Lloyd (2016)).


From an evolutionary perspective, this paper “Towards a scientific concept of free will as a biological trait: spontaneous actions and decision-making in invertebrates” by B. Brembs (2010) describes how animal species have been shown to randomize their behavior to gain an evolutionary advantage. Their behavior is shown to be self-initiated, that is, given the same environment, the same external conditions, animals will deliberately inject variability into their behavior. This is in direct conflict with behaviorist models where environmental conditioning alone determines behavior, but strongly agrees with the indeterminant quantum system described here. Animals go even further, actually increasing the variability of their actions when faced with uncertain situations – seeking to deliberately explore the unknown. A model is described in which animals amplify small random differences in internal conditions to generate this variability: “a neuronal amplification process was recently observed directly in the barrel cortex of rodents, opening up the intriguing perspective of a physiological mechanism dedicated to generating neural (and by consequence, behavioral) variability” from “Sensitivity to perturbations in vivo implies high noise and suggest rate coding in cortex” by M. London et al (2010) hat tip B. Brembs. The paper by Brembs gets everything right short of recognizing two things: (1) while these small differences are indeed random when looked at externally and objectively, the randomness follows quantum probabilities that are dual to the preferences of the organism. Even in an organism as simple as a fly, there is a little ‘self’ in there. Not necessarily offering the same experience as in human consciousness, but free will and a mind’s eye are indeed present: “(flies)…can actively shift their focus of attention restricting their behavioral responses to parts of the visual field.” (from here and here, hat tip B. Brembs). Recognizing this will resolve the conundrum specifically called out in “Downward Causation and the Neurobiology of Free Will” by C. Koch (2009): “for surely my actions should be caused because I want them to happen for one or more reasons rather that they happen by chance” (hat tip B. Brembs). The resolution involves recognizing that “want” and “chance” are dual versions of the same thing! Second (2), while it is tempting, and dogmatic, in evolutionary biology to chalk everything up to “that must have been selected for during X billion years of evolution”, we have pointed out in “What if the Miracle Behind Evolution is Quantum Mechanics?“, that this hypothesis class does, in fact, have infinite capacity, i.e. VC-dimension. That means it can explain anything! Behavioral unpredictability was not selected for by natural selection in evolution as an advantageous trait, it was present in life from the very beginning – all the way back to when life was nothing more than a complex molecule who’s only remarkable property was that it vibrated fast enough to sustain growing quantum entanglement!

VIII. What is it like to be an Electron?

We know what it feels like to be a human being with a mind’s eye and full-fledged consciousness, but what does it feel like to be an electron where the mind’s eye, and even basic memory, is unavailable? We’re not talking panpsychism here – this electron has nowhere near the experience of human consciousness. Have you ever seen the movie Memento? In this movie, the protagonist has a form of anterograde amnesia mentioned above. He cannot form new memories, but his long-term memories from a few years prior are intact. Every few hours or so, amnesia sets in and all recent memories are wiped clean, forgotten. After each episode, he suddenly finds himself in an unknown place with unfamiliar people. He does not know the names of people around him, or how he came to be there. Even if he had spent the last couple hours getting to know someone, it’s all suddenly gone. No recollection. Everyone is a stranger. Every place a new foreign place. This character begins using clever tricks in an attempt to remember – like having signs tattooed on his body, and leaving Polaroid photographs with notes on them in his pockets. These substitute for basic memories. Imagine how that would feel forgetting everything every few hours. Once that sets in, imagine how it would feel as your memory gets shorter and shorter. At the point where you can persist memories for only a few seconds you can forget about any deep analysis. You still have some memory, still have free will, still are able to make choices, but the ones that require any deep thought, or focus with your mind’s eye – forget about it. If you don’t understand something on first pass, forget about top-down reasoning to figure it out. Any self-awareness you had before is irrelevant now because you can never think about it. You have no time to recall any knowledge even if you could remember. Just utter madness! Forget about solving difficult math problems. Forget about working complex puzzles. Forget about having a deep conversation with someone, you will constantly lose your train of thought. Forget about contemplating consciousness, free will, or your role in the Cosmos!

Now imagine something like the electron – remember we are talking about maybe nanoseconds between measurements, between choices. Forced to make choices constantly, billions of times per second. And, every time your memory is erased. You have no memory of where you came from. You have no idea where you are going. No concentration. No focus. No mind’s eye, and so no free will. Choice is forced upon you by the outside world and all you can down is choose. But, you can still make choices. Not choices like you are used to, you cannot push buttons in your brain and move your limbs – it takes too long, takes too much focus, remember the speed of free will? You no longer have self-awareness, that too takes too long to think about. You are just all absolutely, insanely “in the moment”. Only aware of right now! Choices are thrown at you constantly, you have no time to think: Will you turn left, or right? Emit a photon or not? What direction are you facing? Absorb a photon or not? A billion choices per second, it’s so maddening! But, the 1st person perspective is there. And you can make choices. Correction, you have to make choices! And, you don’t get to decide what those choices are. Just in your face questions that you must answer now!

You will seek out stability. But, you will never see it coming. If you chance upon an atom to give you shelter, you can emit a photon and descend into a lower energy state of the atom. Excited states are unstable, you will quickly emit another photon and transition to a lower, more stable energy state. The ground state, if you get there, gives you a moment of peace. If you could dream, your dream would be to entangle with other particles, to become something greater than yourself, to escape the madness, to be able to remember, to have some idea of what’s coming next, to have freedom. But, you cannot.

If that all sounds crazy, maybe you are beginning to appreciate what life is. Life is persisting entanglement so that you can remember your last choice, so that you may know you made a decision, so that everything isn’t just a fleeting instant, so that there is depth to your existence, so that you may have freedom! Life is the Universe’s opportunity to escape the madness. A miracle made possible by quantum entanglement. Indeed, the essence of life is quantum entanglement. And, the engine by which it adapts and evolves is the intrinsic quantum computational power of the Universe! It is precious indeed!

IX. Predictability

In his essay “The Ghost in the Quantum Turing Machine” (2013), S. Aaronson discusses the relationship between predictability and free will. He suggests that if a Turing machine (a non-quantum computer) can consistently and accurately predict the actions of a human then he or she has no free will. This seems sensible enough, but since the source of free will we describe here is a quantum entangled system, and is distinctly non-classical, this assertion requires a modification. Today’s cutting edge supercomputers require 100 days to simulate the dynamics of a single small protein biomolecule for a millisecond (see “Supercomputer sets protein folding record” (2010)). Modeling something like an organism would likely take more than the age of the Universe even using all the classical computers available on Earth. Quantum computers with their vast computing power change things, though, and this is why we would alter Aaronson’s conjecture as follows: if a model can simulate a human then the model has a least as much free will as the human. And, frankly, it could very well turn out that it will take not just a quantum computer, but a quantum computer that implements an NLSE to perform such a simulation. That is to say, it will be necessary to give the model a mind’s eye so that it can have the ability to choose what to think about, where to focus its attention, choose what choices to make, to truly pass a Turing test. Furthermore, to create such a simulator would be to create life. The 1st person perspective is present in all fundamental particles in the Universe and the means by which this grows is through the process of entanglement combining the collection of particles into One thing. Since we would have established the quantum entangled simulator artificially, it may better be characterized as life on life support, but life nonetheless. The system would naturally follow the laws of quantum mechanics, and this would give rise to its own personality in the 1st person. It would, of course, follow the transitions of a quantum system seeking out lower and more stable energy states and this would manifest to it as its own assortment of needs, desires and a spectrum of emotions.

X. The Good, the Bad and the Dual – Further Explorations of the 1st/3rd Person Duality

Despite that we have said quite a lot about the origin of the 1st person perspective, memory, the mind’s eye, free will, and the nature of life itself, we have not said anything about why certain experiences feel pleasant (good) and others unpleasant (bad). Why should anything feel pleasant? Why is there pain? Why are there qualia to experience? Sure, there are studies showing that certain chemicals like serotonin and dopamine are correlated with positive moods and good feelings. They may even be an essential part of some causal chain. But, still we are left asking the question: why does the chemical serotonin feel good? Why should any chemical have any bearing on our feelings? If the 1st/3rd person duality we have described here is to hold, then every phenomenon in subjective experience must have a dual description in objective physics. All those pleasant and unpleasant feelings, all of those wants, desires, pains, and needs must have a dual description not just in disassociated chemical reactions, but directly pertaining to a single quantum entangled system – the self. On the other side, quantum mechanics only cares about one thing and that is: energy states. Generally, systems when left alone “want” to transition to lower and/or more stable energy states, e.g. an electron in the hydrogen atom, in an excited state, will emit a photon to return to the lower, and more stable ground state. So, all the subjectivity in life must be understood in their dual quantum mechanical description as relating to the energy state of the organism’s quantum entangled system.


Too move forward we need to refer to the following paper “Quantum entanglement between the electron clouds of nucleic acids in DNA” by E. Rieper et. al. (2010) which shows that the electron clouds of neighboring nucleotides are entangled in DNA. Moreover, the entanglement helps to hold DNA together and allows it to achieve a more stable energy configuration. To get an intuitive idea of how this works, imagine electrons swirling laterally, some clockwise, some counter-clockwise, around a long double-helix strand of DNA, tugging on it, inducing instability in the chain. When entangled, the electrons clouds slip into a superposition of states so that each electron is half on the right side, and half on the left and balance each other out, sort of like orbiting in symmetric unison, stabilizing the molecule. Similarly, for oscillations along the length of the chain, if neighboring oscillations are out-of-synch, disharmonious, it induces instability in the biomolecule. If the oscillations are synchronized, entangled together, harmonious, like normal modes of oscillation in a classical spring, the energy state is lower stabilizing the molecule.


This is not a new trick of Nature, the nucleus of deuterium (an isotope of hydrogen) is comprised of a proton and a neutron that sit in an entangled superposition of states (an isospin singlet and triplet state, hat tip J. McFadden and J. Al-Khalili) so that they may bind closer to each other. This allows the system to form a more stable nuclear state. Suppose that life takes it one step further, though, and entanglement moves far beyond stabilizing individual atoms and biomolecules and instead entangles biomolecules all over the organism together. Intuitively, to imagine the meaning of all this entanglement, think of a large selection of biomolecules in your body vibrating coherently, synchronized – like a marching band marching together as One unit rather than a cluster of chaotic individuals – stabilizing the organism as entanglement in the electron clouds did for DNA. To provide a guess at how this entanglement could be sustained, we invoke the idea presented earlier that DNA may function not only as a source of genetic code but as a sort of antennae – an EPR photon source for entangling other biomolecules, constantly being driven, absorbing, down converting and re-emitting entangled photons (possibly THz) on femtosecond timescales (faster than decoherence rates) to keep the system entangled together as One unit. This entanglement then may have a stabilizing effect on the organism’s quantum entangled system, lowering and/or stabilizing its collective energy state. If this is true, then several natural, interesting and compelling explanations of dual subjective/objective phenomena emerge.



If we fire any particle, whether it be light (photons), electrons, or something relatively heavy like buckyballs (the molecule Buckminsterfullerene, C^{60} ) through a two-slit interferometer, we will see an interference pattern on the other side. All particles exhibit this wave-like quantum property regardless of size – it’s just that more massive ones have a much shorter wavelength and therefore a narrower interference pattern. When this experiment is performed, it is important, however, to remove all gas molecules from the interferometer chamber. Gas molecules interfere with the wave-like nature of the particles and will ruin the interference pattern. One way to think of it is: if anything in the environment acquires information about where the particle is, like which of the slits the particle passes through, the wave-like nature of the particle is disrupted and so is the interference pattern. If the information is only partial (i.e. not certain) the interference pattern is still visible but obstructed. Once information is obtained definitively showing which slit the particle went through, though, the interference pattern is completely destroyed (this is decoherence).

In the body of an organism, the establishment of entanglement throughout a macro-collection of biomolecules may be like projecting an internal hologram. Holograms are made from interfering coherent light (i.e. light of the same frequency, like a laser). In this case, the frequency is not visible light but probably frequencies like THz that interact with the vibrational states of biomolecules. The hologram is analogous to the interference pattern in the two-slit interferometer described above and is the means by which biomolecules throughout the body are entangled together. It allows biomolecules to be synchronized and brought to operate in unison – as One entity. So that it may, for instance, direct the growth of biomolecules such as microtubules (see “Live visualizations of single isolated tubulin protein self-assembly via tunneling current: effect of electromagnetic pumping during spontaneous growth of microtubule” (2014) by S. Sahu et. al.), or, control gene expression as in “Specificity and heterogeneity of THz radiation effect on gene expression in mouse mesenchymal stem cells” by B. S. Alexandrov et. al. (2013). It is also the means by which a lower and/or more stable energy state is achieved for the collective entangled biomolecules in the organism. When something disrupts this interference pattern, just like gas molecules disrupt the distinct interference bands in the interferometer, this is experienced by the organism as stress. This stress could be mental stress, environmental stress, or physical stress – like being sick. The root cause of the feeling, though, is something is disrupting the stable quantum energy state of the organism. The feeling of stress in the 1st person is dual to this quantum description in the 3rd.


Heart rate variability refers to variations in the heart’s rhythmic beat and is a strong indicator of overall health, including stress levels. See this video “Heart Rate Variability Explained” by J. Augustine (2007) for an introduction. The human heart is a rhythmic organ, intimately connected to the autonomic nervous system, and perhaps this is why it is particularly sensitive to stress – and thereby disruptions of the coherent hologram entangling the organism together. If you experience stress, you probably feel it most pronounced in your heart. In some cases, it may feel like your heart is in the grip of a vice, because the interference pattern synchronizing the whole body, and so important to the heart’s rhythmic operation, is being interfered with. See this paper for more on clinical studies relating heart rate variability to stress “The Effects of Psychosocial Stress on Heart Rate Variability in Panic Disorder” by K. Petrowski et. al. (2010).


There are studies connecting stress to negative clinical outcomes as it relates to all kinds of health issues including digestive, fertility, and urinary problems as well as a weakened immune system. However, evidence linking stress and cancer is still weak, possibly because its development is long term and there are other explanatory covarying factors such as smoking and alcohol consumption that are themselves behavioral responses to stress (see this page by the National Cancer Institute for more).


On the other hand, adaptation to stress is a tremendously positive experience. It feels great to overcome stress. We have explored previously how adaptation to stress evolutionarily (e.g. heat stress, starvation stress, oxygen stress) is a quantum transition or series of transitions to more stable quantum energy states (see “What if Quantum Mechanics is the Miracle Behind Evolution?
for more) and leads to adaptation. This is made possible because of the vast amount of entanglement taking place in the organism. Psychophysical stress is no different. Adapting to stress is a quantum transition to a more stable energy state – a transition that clears up the interference pattern, clears up the hologram bringing stabilizing coherent entanglement to the organism.



In the same way that stress disrupts entanglement throughout the body, causing instability in quantum energy states, we can explore the stabilizing effects of quantum entanglement in the mind through meditation. Meditation is about calming the mind. Practitioners unanimously speak of its benefits and the inner peace it bestows, even though proficiency requires diligent practice (also see here on the health benefits of meditation). In the words of yogi Dada Gunamuktananda, in his video “Consciousness — the Final Frontier” (2014), while Descartes famously said, “I think therefore I am”, Gunamuktananda’s response is “When I stop thinking then I really am!”.


Zeno’s paradox can be described as the action of keeping a quantum state localized by continually observing it. Meditation is the opposite. When we stop thinking we stop using our mind’s eye to direct our thoughts, we stop making choices, we stop subjecting ourselves to measurement. The absence of measurement allows quantum entanglement to grow, it allows quantum superposition to grow. The system must be driven and out-of-equilibrium to do this, yes, but that is the nature of biological systems. In our illustrative example of the mind’s eye it is not making a choice at end “B” or at end “A”, but is letting entanglement flow, the wave function is not collapsed, and superpositions of states expand. It allows the “brain solitons” to delocalize. This entanglement has a stabilizing effect on the organism’s energy state in the 3rd person and feels quite pleasant to you in the 1st. Awareness of the self increases substantially during meditation – a direct result of delocalization.


Another aspect of meditation is its focus on directing a sort of “energy” to certain parts of the body, e.g. an arm, a leg, or the forebrain, etc. The term “energy” is used, but this is not the same as the rigorously defined quantity of energy in physics. However, it does not seem crazy to consider these two terms related. Interestingly, we have seen that the Davydov soliton is thought to transport real energy up and down alpha-helical structures, and, these structures are ubiquitous throughout the body. The Davydov soliton quite possibly could play a critical role in the manifestation of the mind’s eye. And, in meditation, it is the mind’s eye that focuses energy to a specific region. Coincidence? If there was a quantum way to transport energy from one alpha-helical molecule to another, and thereby, from one region of the organism to another, this would make the association of the two descriptions of energy sensible. A quantum mechanism for such transport is not yet known, however, this may be possible through the holographic process of photon exchange we describe above.


If you feel like undertaking an experiment, try this one: the next time you find yourself going through security at an airport and you notice a millimeter wave (a.k.a. THz) scanning device, pay attention to your feelings during the scan. Prior to passing through the machine, try to meditate mildly, calm your mind and increase awareness of your mind and body. See if you can feel the momentary effect, a slight muddling of the hologram, of the THz scan on your quantum entangled self!

A regular meditation practice can lead to a rich set of inner experiences that explore the 1st/3rd person duality. Generally, you can find a plethora of experiences that are immensely pleasant (e.g. the resonance associated with Om in the mind feels incredible, delocalizing, loving, and like becoming One with your surroundings). In each case, the feeling of the experience is dual to a quantum mechanical transition – more stable states feel calm, pleasant, patient, love-like, unifying, while unstable states feel frantic, impatient, scattered, unpleasant.



Everyone unanimously agrees sex feels good. But why? We know that chemicals are released in the body during sex such as dopamine, prolactin, oxytocin, serotonin, and norepinephrine. But, why should these arbitrary chemicals feel great? Are they magic? We know the parasympathetic nervous system is involved, and we know studies of the brain show surprisingly little activity, but it feels like we are saying everything that is objectively correlated with sex, yet learning nothing about why it is a fantastic subjective experience! We’ve talked already about quantum mechanics caring about energy levels, and only that, so, suppose sex is about energy states. Specifically, the creation of a low-level energy state called a Fröhlich condensate. A Fröhlich condensate is a special quantum mechanical configuration of matter that allows a number of particles to entangle and become One thing, similar to the Davydov soliton. It is a precise solution to a form of the NLSE first proposed back in the 1960’s by physicist Herbert Fröhlich. When it forms, an exceptionally low energy quantum state is created and energy is dumped into it. Fröhlich condensates require a driving force to put energy into them – guess what that is? To get an intuitive feel for what a Fröhlich condensate is, imagine people doing “the wave” at a sporting event. This is the phenomenon where a wave of human-hand-raising circles the stadium. When it passes by your seating-section you stand up and throw your arms in the air. From afar, it looks like a smooth wave traveling around the stadium. Each person is an individual oscillator – you can stand up or sit down independently, but when you participate in the wave you synchronize your “oscillations” with the rest of the fans in the stadium and create a different kind of oscillation – a “wave of fans”. You have to expend energy to get it to form and these waves are only temporary but they are a lot of fun and provide a feeling of comradery among people. The hormones and neurotransmitters mentioned above are correlated with, and may even facilitate, the quantum entanglement that accompanies the Fröhlich condensate but they are not the source of the pleasure. Only energy state transitions connected to your quantum entangled self can do that. You interact with this new formed quasiparticle, and while it lasts, feel the pleasure of transitioning into a lower energy state. But, why does Nature do this? Is it just to create good feelings to induce procreation? Possibly. But, maybe, just maybe, the point is to kickstart the gametes with a big dose of quantum entanglement, give them some computing power to find their way on the journey ahead, a warm feeling of Oneness, a spark, to help them on their way, to pass on the gift of life…



Why does it always feel good when we finally understand something? That’s not to say gaining knowledge always feel good, certainly there may be some things in life that we wish we could “un-know”. Understanding is different than knowledge. Understanding is about “getting it”. We’ve all had moments battling to understand an idea, wrestling with it, sometimes seemingly hopelessly, until, suddenly, we “get it”, it all comes together, and we feel great! What is going on in the 3rd person description that is dual to this consistently pleasant experience?

Quantum neural networks are models designed to describe the behavior of neurons in the brain, while also implementing quantum effects, and leveraging quantum computing power. While no method has been found yet that fully integrates quantum with the classical aspects of neural computing, designs for quantum network models usually involve minimizing a so-called “energy” function that both reduces (a) the errors that the model makes and (b) minimizes the square of “synaptic” weights connecting neurons (see this paper “The Quest for a Quantum Network” by M. Schuld et. al. (2014) for more). The purpose of the first is clear – we want the model to learn how to make predictions without mistakes, while the second tends to diversify the model’s dependence across a plethora of “experts”. For example, if you are a juror in a court case, isn’t your confidence in your verdict greater if you base your decision on a diverse array of expert testimony, e.g. DNA evidence, ballistics, eye-witnesses, finger prints, smoking gun, etc., and they all agree? In the case of a neural network each “expert” is a neuron, but the idea is the same. This is a standard procedure in neural network learning (both classical and quantum) and has achieved substantial success in the machine learning community. Still, quantum mechanics only cares about real energy states, what does this “energy” function have to do with real energy? Conveniently, the function that is minimized in the quantum neural network (see Hopfield network) is equivalent to the real interaction energy in something called an Ising spin-glass model from physics. In other words, if the neurons and their connections in your brain can be regarded as an Ising model, then the quantum neural network learns by lowering the real energy embedded in its structure. Experimental evidence demonstrating that a biological neural network behaved like an Ising model was found in “Weak Pairwise Correlations Imply Strongly Correlated Network States in a Neural Population” by E. Schneidman et. al. (2006) studying salamander ganglion cells. This suggests that when you learn something, and that moment of understanding hits you, and a rush of joy comes over you, this is a quantum energy transition to a lower energy state. Of course, for the 1st/3rd person duality presented here to hold, your quantum-entangled-self would need to be entangled with the quantum network, functioning as One system – a fully quantum neural network design would need to be found.

The learning function we described above is actually completely general – it appears in many machine learning algorithms that “maximize the margin” in learning the task of classification or regression. Margin maximization has an Occam’s Razor-like effect – it directly reduces the capacity of the model to “fit” the data, simplifying it, which in turn makes the model produce better predictions. When a model makes better predictions, it is natural to suggest the model “understands” the data better. It actually makes you wonder, are the rules of the quantum mechanics setup to encourage understanding in all kinds of systems throughout the Universe? In other words, in whatever physical systems something like an Ising model shows up, should we expect something that resembles understanding? If so, understanding is not something sought out by just humans, or even just high-level organisms, but it is intrinsic to the Universe itself! Suddenly, the quote below by physicist Brian Cox does not sound far-fetched at all:

“We are the cosmos made conscious and life is the means by which the Universe understands itself.” – Brian Cox, Physicist (~2011) Television show: “Wonders of the Universe – Messengers”

Self-Awareness and Gödel’s Incompleteness Theorem

There is a strange feeling to our self-awareness that is hard to put a finger on. Douglas Hofstadter in his Pulitzer prize winning book “Gödel, Escher, Bach” (1979) explored the idea that the source of consciousness is a kind of “strange loop” that embodies abstract self-referencing ability. The self-referencing fugues of J. S. Bach, the abstract, impossible, self-referential drawings of M. C. Escher, and the self-referential formal math bomb known as Gödel’s incompleteness theorem are examples that triangulate Hofstadter’s concept.


Figure 24: Drawing Hands by M. C. Escher, 1948, Lithograph


Today, self-awareness is widely accepted as a critical step to consciousness and has inspired artificial intelligence researchers to attempt to build self-aware robots. This video by Hod Lipson “Building Self Aware Robots” (2007) shows some of them. The robots start out not knowing what they themselves look like. As they try to execute motion tasks – like moving across the room – they become “aware” of whether they have arms and legs, how many, and, generally, what they look like – and improve their skills at locomotion. There are two parts to the robot’s autonomous command center, (a) the model of itself, which is learned on the fly from data collected in the act of moving, and (b) the locomotion command center which uses (a) to attempt to move across the floor. Each of these takes a turn in operating serially. So, the model (a) of itself updates using the latest collected data, then the locomotion module (b) uses that model to move which in turn generates new data, then feeds that back to update the model of itself (a), and so on. It is an iterative process of (a)->(b)->(a)->(b)->(a)… In the video, you can see the robot’s self-referential model evolve real-time to where it achieves an accurate 3-D representation of itself. While it is remarkable the learning that these robots do, they do not seem to be self-aware and conscious like we are. The module (b) has no understanding of module (a) and vice versa. No real awareness of it. The processing that takes places is still the tunnel-vision algorithmic processing of simple logical gates in a CPU. Still, it does seem like Lipson is on the right track – the self-awareness developed by these robots is clearly necessary for human consciousness, but it does not feel sufficient.

Figure 25: (Left) A “figure-eight” Mobius strip from here. (Right) A two-dimensional representation of the Klein bottle immersed in three-dimensional space. Image and caption via Wikipedia. Self-referencing quantum entanglement in the brain gives rise to the feeling of self-awareness.


R. Penrose in his book “The Emperor’s New Mind” (1989) argues that the difference between the human mind and the machine is that the mind can see mathematical truth in non-algorithmic problems. He said there are certain Gödelian statements that humans, because of their consciousness, can see their truth, but which Turing machines can never prove. D. Srivastava et. al. (2015) summed Gödel up well: “Gödel’s incompleteness theorem shows that any finite set of rules that encompass the rules of arithmetic is either inconsistent or incomplete. It entails either statements that can be proved to be both true and false, or statements that cannot be proved to be either true or false” from here. An example is the following: suppose F is any formal axiomatic system for proving mathematical statements, then there is a statement, called the Gödelian statement of F, we will label as G(F), equal to the following:


G(F) = “This sentence cannot be proved in F ”


The argument is that the system F can never prove the truth of this statement, but its truth is apparent to us. To see this, assume F could prove the statement, then we are lead to a logical contradiction. On the other hand, if F cannot prove the sentence then the sentence is true, again leading to a contradiction. Much has been made of Penrose’s argument with several notable counter arguments (a review is here) and no definitive resolution. Whatever the formal case may be with Penrose’s argument, true or not, it does seem that it does capture some essential elements of human consciousness – something “rings true” about it. Something feels strange about these kinds of self-referential loops and so a natural question is what kinds of quantum mechanical phenomena are dual to this subjective, albeit vague, 1st person description? We will suggest there are three essential aspects of quantum mechanics at play here:


I.) Quantum systems have the capacity for self-reference through quantum entanglement. The Gödelian statement above is obviously self-referential, but the serial self-referencing ability in Lipson’s robots does not seem to capture it. The crisscross entanglement we have described here, the self-referencing capacity of the NLSE, does. The difference is the wave function in this case loops back onto itself, but, because of entanglement, it is always One thing. Just as the Gödelian statement above must be evaluated as one mathematical statement. Lipson’s robots would need to entangle module (a) and module (b) together so they function as One thing.


II.) Quantum systems can be in a superposition of states, simultaneously spin up and spin down. Abstracted so spins represent a Boolean qubit, it is perfectly fine for a statement to be both true and false at the same time. Consider this version of the above Gödelian statement:

G(F) = “This statement is false”

If we try to iteratively evaluate this statement (like Lipson’s robots), we might start assuming the statement is true. Ok, so it is true that this statement is false, then we conclude the statement is false. Ok, if false, then it is false that this statement is false, then we conclude the statement is true. And, we are back to where we started. We can iterate through like this forever and never understand this statement. It will never converge to one answer. Only with a quantum entangled system can we model the essence of this statement, that it is true and false at the same time, in a superposition of states, never converging to one or the other. Since you are a quantum entangled system, that’s ok. You can model this statement. Consider this version:


G(F) = “I cannot prove this sentence”


This might be your Gödelian statement. You cannot prove it true or false without leading to a contradiction, but you can model it in your mind, you can understand it. Your mind is not a classical system governed by classical logic.


III.) The last quantum mechanical trait at play here is the ability to evaluate infinite loops instantaneously. In physics the problem of solving the Schrödinger equation is something that Nature does instantaneously even though it involves non-local information. For example, the solutions to the equation that describe a particle in a box look like the standing waves that would fit in that box. But suppose that box is inside another bigger box, and we suddenly remove one of the walls, Nature will instantaneously solve the new Schrödinger equation for the bigger box. These new solutions will look like standing waves in the bigger box. Another way of looking at this is from Feynman’s path integral perspective. The path integral formulation is equivalent to the Schrödinger equation, it’s just a different way to model the evolution of a quantum system. If we want to ask how does the state of some electron change with time (e.g. upon removal of a wall of the box) we can calculate infinitely many path integrals over all possible ways the system could evolve and sum the “amplitudes” up instantaneously and this would describe the time evolution of the system. Fortunately, we have calculus to integrate this infinite sum. In either case, Feynman or Schrödinger, the point is Nature considers infinite non-local information in quantum mechanics all the time. Now, consider the following issue with our first Gödelian statement. We can simply say the statement G(F) is now an axiom in a new stronger system called F’. Then have we plugged the hole created by Gödel’s statement? The answer is no, because we can always construct a new Gödelian statement for the new system F’:


G(F) = “This sentence cannot be proved in F’ ”


We could add a new axiom to F’ and create F”, but then we would just create a new Gödelian statement for F”, and so on forever (for a much more thorough treatment of this process of “jumping out of the system”, see Hofstadter’s Gödel, Escher, Bach)… If we operate with blinders on like a Turing machine, not seeing the lack of convergence at infinity, then we could iterate through this process forever. A Turing machine would have no way of knowing this iterative process would lead nowhere. But, in the right quantum system, we can count on Nature to evaluate this infinite loop for us, to solve the Schrödinger equation. Like finding the standing waves that fit in a sort of recursive neural circuit. We feel this when we think about this self-referential puzzle, our quantum minds are modeling this statement, we find a quantum solution, and we feel the true nature of the statement. Another way to think of this is just to consider the version of Gödel’s theorem in b.) above. We can iteratively evaluate it again and again, True, False, True, False, and it will never converge. This infinite series, also, can be described in some kind of quantum circuit in the mind. Nature does this infinite calculation for us, sums all the paths, all the amplitudes, and it is clear to us that it will never converge to a provable statement. The solution to the Schrödinger equation for the quantum circuit corresponds to a superposition of true and false. Just like Nature finding that an entangled superposition is the solution to Deuterium (energy minimum in the nucleus). It is formally undecidable classically, but representable in a quantum circuit.

Interestingly, I do not feel I can ever retain an understanding of Gödel’s theorem in long-term memory. Every time I recall it, I have to think-it-through a few times before I feel I understand it again. I wonder if this is the inability of a classical system, the neurons and their connections, to adequately describe Gödel’s statement. Perhaps I have to think-it-though each time to conjure up a quantum model in my mind. Only in my quantum mind, in short-term memory, can I adequately represent its self-referential nature, the simultaneous truth and falsehood of the statement.

General Qualia of the Senses

Red, yellow, blue, hot, cold, pain, tickle, joy, fear, hunger, (hat tip here for the suggestions) are all qualia of the senses. Why do these things feel as they do? In other words, why does yellow appear as the color yellow? Why should it appear as a color at all and not just feel as does sound? Both are waves. The frequencies of visible light are expressible in the trillions of hertz, far outside the audible range (20-20,000 hz). There would be no confusion as to the origin of the signal. Why not map both these inputs onto the same perception? Both systems are directional, you could just have an image in your mind of where any and all waves were coming from. Think of how a bat must “see” with its sonar, for instance. In the duality we have described here, all 1st person subjective phenomena must have a dual 3rd person quantum mechanical description as it pertains to a single quantum entangled system – the self. There must be a quantum signature to all these phenomena. The quantum effect of light absorption on the quantum entangled self must be qualitatively different than the quantum effect of sound detection. What is the difference in these quantum signature effects? Could they each induce different kinds of quasiparticles? Maybe light generates a spectrum of magnetons, while sound induces a spectrum of phonons? The feeling of color would then be the subjective dual to a magneton rippling through the quantum entangled self, while the feeling of sound, the dual to phonons vibrating thru.


Interestingly, the human eye has recently been shown to be able to detect single photons providing an example of how the brain is sensitive to quantum-level effects. Perhaps a useful way to think about the distinction between the macroscopic brain and quantum mind is in terms of classical versus quantum information. Classical information will tell you what’s in the world, where it is, what color it is, etc., but quantum information will tell you what it feels like.


Moral Responsibility

Philosophers since Aristotle have argued that free will is a necessary requirement for moral responsibility. For if we are not free to make choices then how can we be held accountable for our actions? Recent studies in the field of Quantum Cognition seek to understand if human behavior can be modeled using quantum effects. For example, when psychologists study how people play the game known as the Prisoner’s Dilemma, their behavior looks irrational. Players can maximize their “reward” in the game by “defecting” and ratting out their colleague (the other prisoner). But, they don’t do this. They tend to “cooperate” refusing to confess or blame their colleague for the crime and accepting an inferior game theoretic outcome. It is interesting though that if quantum effects are applied, and we assume quantum entanglement between the prisoners, the experimental results are predicted accurately. In the 1st person, this may manifest as our feeling of empathy for others. In this article “You’re not irrational, you’re just quantum probabilistic” by Z. Wang (2015), she provides an overview of quantum approaches to psychology. The trouble is that it is difficult to describe a physical system that can maintain entanglement between organisms. One guess starts with the fact that the brain does emit brain waves. If these brain waves were comprised of photons from an EPR source, and emitted in sufficient quantities, then it is conceivable that absorption of them by another organism could create cross-organism entanglement. A variation on this scheme could be related to eye contact. In this case eye contact would be somehow instrumental in the entanglement – e.g. incoming light is absorbed in one person’s eye by biomolecules (e.g. DNA), down converted, and re-emitted as lower frequency entangled EPR photons, and, finally, absorbed by the second person entangling the organisms together. The reason for singling out this particular mechanism as a means of entanglement is sourced in the powerful feelings that arise upon making eye contact, especially prolonged contact, with another individual (see this video for example). Another possibility is that the entanglement is present but exists entirely within the brain of each individual. For instance, imagine two piano players making music together. It feels joyful to each, the sounds resonating together, the surprise of what improvisation the other musician will add next, the harmony. But, in this description the entanglement can be seen as taking place between phonons within the auditory centers of each individual brain. Analogously, people empathizing with each other could be more like making a sort of ’emotional music’ together but the quantum entanglement resides entirely within each individual. Whatever the case may turn out to be, the feeling of empathy in the 1st person could be derived from some form of quantum entanglement in the 3rd. The simplistic models of quantum cognition would be an approximation to a much finer biological entanglement, but sufficient enough to predict the outcomes of these psychology experiments. Interestingly, “question order” is another psychological puzzle that looks irrational from a classical perspective but is explained naturally by quantum mechanics, although not relating to entanglement.


But, empathy alone would not seem to explain moral responsibility. Children start out exploring, doing the wrong thing and making mistakes, not because they are malicious but because they do not know better. It takes time to learn what the right thing to do is. It can be very difficult, even as an adult, to stay on the straight and narrow path of trying to do the right thing. Even the best of us have some missteps along the way. In this article “Aristotle on Moral Responsibility” (1995) author D. Hsieh sums Aristotle’s views up thusly:


“[Aristotle’s] general account of freedom of the will, coupled with [his] view that virtue consists in cultivating good habits over the long-term implies that ‘the virtues are voluntary (for we ourselves are somehow partly responsible for our states of character).’ (Aristotle, 1114b) We are responsible for our states of character because habits and states of character arise from the repetition of certain types action.”


Children choose what choices to make with their mind’s eye. They follow their preferences which are dual to quantum probabilities. Initially many of these preferences are exploratory – the whole world is new to them! Over time some of these decisions lead to negative outcomes, some lead to positive outcomes, some lead to short-term positive but long-term negative outcomes (local maxima). Neural connections are rewired in long-term memory as a result of these experiences which in turn affect the preferences of the child. Probably quantum computing is involved to solve some of these difficult and highly nonlinear connective questions, then solutions are relayed to long-term memory through the quantum tickertape of short-term memory – i.e. understanding what the “right thing to do” is. Adult guidance is certainly helpful too. Empathy affects lead to an understanding of “do unto others as you would have done unto you.” From these experiences, some advice, and sometimes some deep deliberation, morally responsible preferences are developed in the quantum-entangled-self. We are still free to make choices, still free to choose to contemplate heinous actions, but our preferences are there, and, through which, we are ultimately constrained by quantum probabilities.



Ok, we’ve said a lot about more stable energy states equating with pleasant feelings, but what about vices? Certainly, there are things in this world, temptations, desires, that feel pleasant, at least in the short term, but we don’t feel they are really good for us. What’s going on there? This common phenomenon would seem the feeling of transitioning quickly into an easily accessible energy state when another state, maybe a more arduous transition, but a substantially more stable state, was an alternative. It is trading a short-term pleasure for long-term stability. It is succumbing to temptation and not staying on the more stable straight and narrow path. Quantum mechanically it is transitioning into a potential energy well that is a quicker transition, but unstable while foregoing a transition into a potential energy well that is much more stable, albeit not as quickly accessible.



The greatest of human emotions, it overlaps a bit with meditation. It also has something to do with two organisms entangling together as One. It is kept going by adapting to stress together, transitioning to a more stable energy state as One. The rest we leave to the reader to discover!



All of the above.




In conclusion, if we assume a 1st person perspective is present in fundamental particles, and we assume that some theories regarding maintaining quantum entanglement in biological systems are experimental proven, a compelling picture of life as a narrative of growing quantum entanglement emerges. As entanglement grows, a sense Oneness is present, basic short term memory develops, quantum computing power enables problem solving and creativity, then a mind’s eye, self-awareness and consciousness itself emerge. A compelling description of many subjective phenomena emerges once we view ourselves as a quantum entangled organism. Descriptions such as “the whole point of your body is to sustain quantum entanglement, that is, to keep you alive” seem apropos! Indeed, quantum entanglement feels as if it is the essence of life itself!


“Western civilization, it seems to me, stands by two great heritages. One is the scientific spirit of adventure — the adventure into the unknown, an unknown which must be recognized as being unknown in order to be explored; the demand that the unanswerable mysteries of the Universe remain unanswered; the attitude that all is uncertain; to summarize it — the humility of the intellect. The other great heritage is Christian ethics — the basis of action on love, the brotherhood of all men, the value of the individual — the humility of the spirit. These two heritages are logically, thoroughly consistent. But logic is not all; one needs one’s heart to follow an idea. If people are going back to religion, what are they going back to? Is the modern church a place to give comfort to a man who doubts God — more, one who disbelieves in God? Is the modern church a place to give comfort and encouragement to the value of such doubts? So far, have we not drawn strength and comfort to maintain the one or the other of these consistent heritages in a way which attacks the values of the other? Is this unavoidable? How can we draw inspiration to support these two pillars of western civilization so that they may stand together in full vigor, mutually unafraid? Is this not the central problem of our time?” – Richard Feynman, physicist


Author’s note: Feynman’s “Christian ethics” seems to refer to those morals that people of all spiritualities hold dear.
