What Is Entanglement Anyway? Chris Fields

Entanglement or non-separability is the core idea of quantum theory. It is a simple idea: the universe is not a bunch of independent parts, but is rather one entity that evolves through time as one entity. That's it. The problem is that this means there's no such thing as causation. This is very hard to wrap your head around. Quantum theory is extraordinarily accurate, and our knowing quantum theory is why we have things like cell phones and computers. But what is quantum theory, really? Why is entanglement its primary prediction? This talk will explain what quantum theory is. I will show that quantum theory has nothing to do with tiny particles, wave-function collapse, or Schroedinger's cat. Quantum theory is about how observers obtain information about the world. It is, in particular, about how observers who have memories and use language obtain information about the world. It is, in other words, about how you and I interact with perfectly ordinary things like tables and chairs and each other. You will leave this talk with a new understanding of quantum theory, and a new appreciation for entanglement.
Chris Fields is an interdisciplinary information scientist interested in both the physics and the cognitive neuroscience underlying the human perception of objects as spatially and temporally bounded entities. His current research focuses on deriving quantum theory from classical information theory; he also works on cell-cell communication and cellular information processing, the role of the “unconscious mind” in creative problem solving, and early childhood development, particularly the etiology of autism-spectrum conditions. He and his wife, author and yoga teacher Alison Tinsley, recently published Meditation: If You’re Doing It, You’re Doing It Right, in which they explore the experience of meditation with meditators from many walks of life.
Dr. Fields has also been a volunteer firefighter, a visual artist, and a travel writer. He currently divides his time between Sonoma, CA and Caunes Minervois, a village in southwestern France.

Interesting to think about the fact there is nothing special about observers, when we are so focussed on human observation as being so separate from nature

[@simesaid]

Did you mean that it's interesting in the sense that we humans tend to see ourselves as somehow "seperate" from nature because we are conducting science _on_ nature? Personally, I find it odd that since special relativity an "observer" has simply referred to _any_ putative particle occupying _any_ possible coordinate in spacetime, and yet (at least as evidenced by the three questioners at the end) people still seem unable to extricate _themselves_ from occupying a central role whenever the term is employed. It's somewhat depressing that following a half hour lecture during which Chris focused on only one point - that designating oneself as a separate, extended, entity within spacetime is a purely arbitrary excercise, an "abstraction", an "imagination", an artifact of viewing the classical world as being somehow "real" as opposed to it being a "model" - that at least someone present didn't get the message. And Chris seemed somewhat deflated, too. Despite what he said, I don't think that he could have made the slides any more basic! Have a great day!

[@markfernee3842]

This is not a closed case. Quantum theory has a measurement problem. This is outlined in excellent detail by John Bell in his Physics World article, "Against measurement". There is current research in the foundations of physics that explores the nature of what constitutes a measurement based on the Wigner's friend paradox.

Anybody familiar with Zeno's paradoxes would have immediately "got" this wonderful talk. The reason that we can't make the archers arrow move through space or time is that there is no way to make sense of space or time _in_ spacetime! Or, to put it another way, spacetime makes no sense. And I say that as one of Einstein's biggest fans! On another note, I find it odd that since special relativity an "observer" has simply referred to _any_ putative particle occupying _any_ possible coordinate in spacetime, and yet (at least as evidenced by the three questioners at the end) people still seem unable to extricate _themselves_ from occupying the central role whenever the term "observer" is employed. It's somewhat depressing that following a half hour lecture during which Chris focused on only one point - that designating oneself as a separate, extended, physically individual entity within spacetime is a purely arbitrary excercise, an "abstraction", an "imagination", an artifact of viewing the classical world as being somehow "real" as opposed to it being a "model" - that at least someone present didn't get the message. And Chris seemed somewhat deflated, too. Despite what he said, I don't think that he could have made the slides any more lucid to apprehend!

[@timmiltz2916]

This lecture could also probably double for marital counseling. I do so love the presentation. I can sense the passion in his message. As soon as he said remove all the parenthesis in the room (different object 'types'), I quickly found myself looking for the lowest common denominator as to a particle. I didn't settle on one heh- for a SPLIT second I settled on Higgs-Boson PRE MASS - where it merely has the POTENTIAL for mass as the 'smallest' so I could remove all parenthesis. I like the concept of 'alocality' vs 'non locality' where alocality hints of stepping outside any framework of space/time models. Easily put in words ! heh But maybe we need a model that can nullify space time, which would explain entanglement, because you'd be saying 'from THIS perspective- there is no space- therefore no distance between both qbits'

Wow! That parenthesis example was brilliant 👌🏼

[@cometrider2000]

[@rodschmidt8952]

My current impression is that entanglement is a necessary consequence of two principles acting simultaneously: conservation and uncertainty. We have (for example) two particles whose angular momentum totals zero; at the same time, individually, the angular momentum is uncertain.

The irony of "This is why physics is possible." being in parentheses makes me want to entangle my fist with the projector screen whilst Dr. Fields observes.

[@pep-lluismolinet342]

I liked the concept of parentheses to explain observation. This is an interesting way to express a known idea: You could model an isolated physical system and its observer together as another isolated physical system, that is, "move the parenthesys" and then there is no observation or colapse of the wave function. But I don´t understand why he says that entanglement is not in contradiction with locality.

[@cz1mmt]

I really enjoyed this explanation. I have a mind for thought experiments but lack the formal mathematical education. However, I believe that allows me not to be limited by the structure. My personal speculation has been we are unable to find a unified theory because our math is based on outside third party observation. It's not until we create a form of looking from within will we possibly achieve a universal theory. I believe this lecture has confirmed my thought process. Thank you.

[@sandrocavali9810]

this is the lecture I was looking for, scientifically skeptics at play, I like this

[@EdwarddelaRey]

This is pure systems theory applied to observers, and so in itself is just a Systems interpretation or model of observers. I like the idea of the boundary being the surface where the interactions are visible; a canvas in effect to be written on to. It dovetails with the ideas of Katya Walter in her Theory Of Everything utilising the i-ching, and also the computation possible at this boundary which I am investigating. Thanks. Interesting exposition.

[@jamesdolan4042]

I had always thought that entanglement was a known predictive behavior between two quantum particles that had interacted with each other. The predictive behavior of the paired particle only occurs if and when an individual particle of the pair is measured.

[@theway5258]

It was very clear explanation. And yes on the fundamental level nothing happens I agree. Hierarchy and filtering are the keys of material world self processing. About memory - a state could be reptoducing with some aberration looply in others observers.

[@jakebob7030]

An explanation into what Chris Fields was saying: For there to be an explanation of what an observer says he sees he must first say he sees it relative to what he doesn’t see but only if that which is observed is only visible to others who are not looking at it at the precise time it disappears and can then not be observed again without taking acid. Last year I couldn’t even spell fissacist and this year I are one.

Wonderful lecture actually

[@hillwalker8741]

Interesting way of getting to the basics - finally I have a veil lifted on what physicists mean when they say 'information'. I am flabbergasted that no one has ever mentioned The No Signaling Theorem before. If it's right then that explains why there is information and entanglement. So why is it just a theorem? Also this is somewhat understandable when we are just talking about vision of the spatially separated. But not so easy with our other senses especially in close proximity. What if I get close to an observer and pick it (you) up. Do quantum mechanics then dissolve and classical physics take over?

The only thing I picked up from this presentation was the idea that objects, things, you and me are all just collections of fundamental particles which are optionally classified into objects, things, you and me. The classification amounts to placing brackets around collections of fundamental particles.

[Correct Meaning of Entanglement in Quantum Mechanics, and Consciousness and Telepathy] In quantum mechanics, the exact notion of entanglement does not mean that a physical signal is transmitted at an infinite speed, but always the truth (or reason, or absolutely right logic) is always present everywhere, regardless of the space and time of the physical world. There is no way that the consciousness of an individual can be transmitted at infinite speed to another physical entity, but it is possible that the same (or relatively complementary or correlated) logic is being physically carried out simultaneously in different places. If we know that the same (or correlated) logic is on processing at the same time in another places, it can be understood that consciousness is delivered at infinite speed. Imagine the actions of identical twins (or exactly oppositely operating coupled systems) that are temporally far away, taking into account of their different surroundings. And, if two people who are far apart are in the same desire, they may be thinking the same thing. There should never be any confusion between physical and logical things. If you know that the most bottom of the physical world is the immaterial reason world, and on the above of it, the physical worlds of continuous-but-finite energy exist, and again on top of it, the worlds of quantum material exist, you have no doubt and understand all things of the whole world together into one.

[@njack1994]

I am not a physics expert. My only question is to understand physics is to understand the relationship of particles to the empty nothing that separates it. I had this thought that what if you apply texture to that empty nothingness. We often think of gravity on this enormous scale but wouldn't every atom and every particle exhibit some sort of gravitational force? In that context think of that empty nothing as a fluid. The more particle occupying a given space will basically displace the empty nothing just like a piece of metal sinking in a lake. As the hunk of something sinks it creates turbulence in the water. Particles would do the same thing. This is where i think people get confused with wave particle duality. granted im out of depth here but that particle traveling through the empty nothing creates gravitational turbulence. Stretching it a bit that empty nothing is what defines the consciousness to even contemplate this. We never understand memories because time is not linear it is merely organized linearly for efficiency of resources. what ever just a thought. My only advice is to not ride the line of what is and what isn't because things start to forgot which side is which :)

I think there is the conflation of distinct terms that problematize our conceptions of the world at the quantum level: 1. parentheses being arbitrary is not the same thing as parentheses being unimportant. I think that is partly the problem. 2. There is another idea to be considered: just because something is of too small a scale for us to measure accurately does not necessarily mean it is not classical. Statistical probabilities are utilised to approximate measurements of a world too small for us to accurately measure. This does not mean this world is necessarily probabilistic either. 3. Numerical quantification is not equivalent to meaningful aggregation (species; principles).

[@douggwyn9656]

Also an important property of "the world" is missing: consistency of each interaction of observations (much as in category theory). The "interfaces" are subjective, but they are not arbitrary.

[@RickDelmonico]

The mind is a multidimensional mapping of some form of probability space where the information is stored in the relationships and the meaning is generated in time as a fluctuating exchange of relationships that follows a power scaling law in which very small scale fluctuations are far more common than large scale fluctuations. The best model to describe this would look like the internet, in which some aspect of spacetime is scale dependent, although some form of synchronization is necessary (entanglement) and the dimensions extend into the probability space as a computational geometry that can only be described approximately rather than discretely, in other words the idea of a three dimensional coordinate system is insufficient in describing the relationships. The mind uses these maps to represent the reality it is perceiving. There is no comprehensive description of the fields involved at present. One of these fields could be described as an intentional field in which the information about the emotional state is far more nuanced and energetic than the information about the logical structure contained in the field. The material expressions we encounter are generated by the fields and the brain is some form of antenna reading the fields.

In the derivation of Bell's Inequality, he posits a presumptive hidden variable, λ(x,t). One member of the twin particles has a position +x at time t, while the twin has a position -x at time t. But note that Bell blithely adopts a common master clock, t, so that λ(x,t) can be algebraically canceled out by λ(-x,t), regardless of the function λ(•). If you appreciate that a gravitational gradient perturbs timekeeping so that the particles speeding off in opposite directions age at their own idiosyncratic rates, then one can no longer algebraically cancel out λ. The derivation of Bell's Inequality breaks down; the presumptive hidden variable λ(x,t) remains present. Indeed one can say the hidden variable is time itself. That is, in reality, each particle ages according to its own local clock, rather than being governed by a common master clock. In Aspect's experiment, λ(x,t) could be Maxwell's Equation for the photon, or (equivalently) Feynman's rotating vectors. But recall that photons traversing a gravitational gradient gain or lose energy and thus change their wavelength (or color) accordingly. The two photons are thus represented by sinusoids which are not perfect mirrors of each other and thus cannot be algebraically canceled out. They will have a residual nonzero "beat frequency" which remains present, thus spoiling Bell's convenient cancellation of λ(x,t) midway through his derivation. That's why Bell's Inequality doesn't hold in the real cosmos where there is no universal master clock that keeps identical time everywhere and everywhen. The not-so-hidden variable is time, itself.

The presentation didn't really get the point.

So you always need ONE COMMON wave function for all particles, which is living on configuration space R^3N.

I know that the answer is 8 minutes, but he says with electrons the interaction is instantanious. Or did I missunderstand this?

[@randywheeler5984]

He certainly puts high stakes in the Associative Property of math , having mentioned it in some way 47 times in 38 minutes. Unfortunately he did not take account of the other properties, Distributive and Communicative. In order to "regroup" an observer out of the World set he subtracted an observer from the World set and added it to the environment, which is identical to adding a negative one. Then he claimed that simply regrouping things was OK. The fallacy is no such thing as a negative observer. In effect he was subtracting a positive one. Changing the Association of a subtraction violates the Commutative property. You are not allowed to swap the arguments when subtracting. 10-5 is NOT equal to 5-10. Indeed, this is a lesson that was taught in elementary school. but you have to obey all of the rules, not just your favorite ones. A bit more care with arithmetic is warranted. According to systems theory, a "System" is a set of entities that work together to product specified effects on their environment." Things that don't participate are not in the set because they are not needed. In this case the Observers were moved into and out of the World System set willy nilly. If the Observer was in the World in the first place it was participating in the World to produce some effect. It could no longer perform that function when removed. For example, if you take your speedometer out of the car it can no longer report speed to the driver, an internal observer who needs it to control the speed. You can't remove your speedometer without changing the essence of the car. ---- Let's cut the confusion and get to the title of the talk ---- The quandary about Quantum Entanglement is that it happens so quickly -- at any great distance -- that it violates the speed of light limit. Zero time is still zero no matter what is between the entities. This only takes two observers and we can ignore what the "World" is between them. Conclusion: something unexplained is happening here.

[@TheForce74]

There is only ONE particle. All particles we observe are just projections of this "master particle". Because the master particle itself is not bound to spacetime and its projections in 3d space undergo individual transmutations due to differing spacetime entries, paths, collisions, etc, it appears to us as different particles with different properties. Similar to a 4 dimensional mirror cabinet. This view resolves all abnormalities of the quantum realm and can be applied to consciousness as well. There's just one "I", but with different perspective, history, spacetime coordinates, etc. In that sense we're identical and different at the same time. Another duality pair that seem incompatible but can coexist simultaneously. Subjective/objective, Particle/wave, space/time, energy/matter, religion/science.

[@davidhand9721]

I've always thought about observation this way, but I was sure this was at odds with QFT and QM. Any time I criticize the specialness of the Copenhagen observer, physicists roll their eyes and defend the idea. It's always seemed inconsistent to me that an electron hitting a screen should be fuzzy and indeterminate, the photons bouncing around in the atom permit electrons to be cloudy, but add a human to the system and somehow the position and momentum have to take a definite value at a definite moment. My observation of that system takes place through countless intermediate steps that all resemble the system without my presence - it's all electrons, baryons, and photons bouncing off of each other, all the way down. It also seems like information is being created on the spot when the "waveform collapses". I don't perfectly understand quantum degrees of freedom, sure, but I know that position and momentum are degrees of freedom. The need for a random number to be generated is quite clearly an addition of information. QM quite clearly demands the random number by insisting that the exact values of these variables are incalculable at previous moments. What bits are lost to make up this difference for the total, which is supposed to be conserved?

This is very interesting talk - connecting quantum mechanics and information theory in this way. I was wondering what if any conclusions could be made in a statistical sense by say averaging over all possible subsystems communicating with every other one? Would this give - I don't know - an average temperature of the universe? Could the total age of the universe impose some constraints on the maximum number of sub-components?

[@cartermonroe4377]

This cannot be done, unfortunately, with Feynmann Dyson Integrals. They can only compute what a regular computer (turing machine) would compute. And computers don't have any hunches or imagination.

[@cartermonroe4377]

+Carter Monroe In the case of Feynmann's brilliant work, all the hunches and imaginations came out of his incredible brain, which I dare say was the best brain ever designed by God.

I understood exactly nothing, but I enjoyed the gobbedlygook.

I really wish this guy would do a video debunking the mysticism that's grown around the layperson's grasp of the Double Slit experiment. Those idiots seem to think that there's something supernatural going on re: observing. It really seems like no one has ever bothered to explain to them the mechanics behind what 'observation' actually entails. This dude explains the hell out of it here. He should take the next step and de-mystify the Double Slit experiment.

[@cellofingers]

At 4:20 he also talks about the "U with the eye". Not too sure what's going on here.

[@peaceonearth351]

Point A and Point B are the same identical appearance and it doesn't matter in how far they are apart.

[@tsjasmine28]

I found this really confusing.

[@johntoobad4705]

This has more to do with smoking weed than it has to do with Quantum mechanics. If you are confused, the answer is simple: inhale more deeply.

[@sclogse1]

+Nathan Patrick I keep thinking that maybe..."when we interact with a system we change it", that we're not really interacting with it at all. It's not changing from what we're doing. Our relativity to it is changing. We're outside a giant stadium guessing what game is being played due to the sounds from the crowd.

[@winston_vanderbilt_ll]

I think "spooky action at a distance" wraps it up quite beautifully.

[@gyrfalcon16]

That's because the guy talking about it doesn't have a clue, and is confused himself.

[@ps200306]

This is the most tiresome BS since Fritjof Capra. Some people really _do_ need to "just shut up and calculate".

[@ISHOULDAKNOWN]

@ 1:40 - "This is why physicist take acid. I'm not kidding." . . . hee hee hee

[@chetanpatil1654]

Great

[@DemetriusFuller]

Already blowing my mind at 12:53. No parentheses.

[@Fransamsterdam]

If you think you can understand fundamental physics only without parentheses, this is your vid!

this guy is awesome

[@TheEtbetween]

How?

[@asachildtobecome]

Entanglement. I find the word itself most interesting from the point of view of unconscious knowledge. Precisely, it means "to bring together into a mass of confusedly interlaced threads. Messy weaving....I vote that when the time comes for science to figure out how EVERYTHING is connected, the word entanglement may be changed to..ta..da! Interlaced. It means exactly the same but without the messiness. This so arrogant of me, n'est pas? Oh heck, I'm having fun...yet, why not? Because as a knitter, entanglement is sure messy, even frustrating.

[@_John_Sean_Walker]

When people say in a talk that (22:22) Einstein was wrong, I always place that talk between brackets.

[@iamtheiconoclast3]

But the fact that Einstein was wrong in this case is basically scientific consensus now, no? Isn't that what Bell's theorem was about? Didn't von Neumann at least and many others agree with this? Hell Einstein was even wrong _about being wrong_ about the cosmological constant. Smart people are wrong all the time. He wasn't omniscient; just very bright and deeply interested in trying to sort out the universe.

[@_John_Sean_Walker]

@@iamtheiconoclast3 Entanglement having to do with nonlocality has in my view nothing to do with Bell's theorem. In my opinion, entanglement has nothing to do with nonlocality. In the university lab entanglement starts with two photons becoming entangled. But you could also say that everything is nonlocality. Like we can say that everything is entangled. How can we compare the two when we don't exactly know what either of them is? Like someone analyzing black holes by using entropy.

[@kees-ft1yb]

The same interface screen can be applied to observe time. It means that you see 1 moment out of all still available moments. All time , past and future exist as a static state. You just move through these states and think that time is moving, but it is not. Only the interface screen is moving. Just like playing a movie forth and back. So this means there is no actual time. So in theory you should be able to go back in time. But everything in the universe is in motion from a high energy state to a low energy state. So you have to put energy in the system. You can slow time by putting energy in a moving object. But it only slows time for the interface screen. Not time itself. ( dejavu?)

[@neurophilosophers994]

Basically he’s saying that the perception of separation of energy as matter is an illusion and observers are not special in this regard. And if an observation is actually the same as an interaction because all things are just one system of energy then you can’t define it as things in different states because the entire system is in one state all the time. It’s the illusion of these as he names parenthesis essentially a reference frame of space time that makes you think that there are things happening but actually that’s the very nature of the illusion from creating the parenthesis in the first place. At the end the question of predicting your own state as impossible without self referential quantum mechanics is just a verification of the idea.

[@paulbenavidez123]

Chris, if i am understanding parentheses correctly in your lecture, panpsychism could not be possible with parentheses? I am certain I am simplifying your argument. Parentheses equal boundaries? In other words, the prefrontal lobe has been highjacked sometime in the not too distant past, maybe about 16,500 years ago and parentheses were created simultaneously of acquiring the pathology of hoarding possessions and therefore boundries? In other words, 2 million years of the nomadic evolutionary model forging the non-parenthetical template was corrupted when we shifted into the sedentary year-around settlement paradigm 16,500 years ago where hoarding possessions began among other behaviors that created the parentheses? I know that I am expressing my understanding of your lecture in anthropological terms. But in terms of panpsychism how could we access our Universe with parentheses?

[@philoso377]

Three life time sentences inmates given an opportunity for freedom were asked to fix a peculiar event others can’t explain or they will remain in jail for life. They are former (1) lawyer (2) day dreamer and (3) mathematician. None of them are classical physicist. In less than three days they were released with a solution, quantum mechanics.

[@davnbull]

Please if anyone with the knowledge could be so kind, I hope to get a response to this: If the axis of the spin of the first entangled particle is measured/ detected, forcing the opposite spin for the second entangled particle, what if a 0 or a 1 (binary code) is assigned, by the measuring device/ detector of the second particle, to a computer? And for every change in the spin measured of the first particle, the opposite 0 or 1 binary is then respectively assigned to by the detector of the second. Shouldn't we be capable, then, of building a computer with the technology to send information instantaneously and faster-than-light at any fathomable distance? Shouldn't this mean that information, coded in binary, could instantaneously travel across the world? The end of internet buffering? Couldn't this mean communication could instantaneously travel between astronauts in orbit and ground control on Earth? Couldn't data scanned by deep space probes onto computers then robotically alter the spin of these coded entangled particles aboard, providing faster-than-light data back to the Earth? Solar System and Space exploration statistics could reach us without delay, I would assume, should such a computer exist. Or is this already the basis for quantum computing?
