How did he prove that ?

Best talk on this topic I've ever seen.

Dr. Spekkens gave a very brief but good description of several areas of human study. The discussion of logic, philosophy and reason as linked to the mathematics of quantum mechanics was very enjoyable. The very best part was in the opening discription of supporting the already proven known facts of nature, physics!

Thanks for making such a weird subject a little more comprehensible. Nice talk.

This was a very interesting lecture which postulates that some interpretations of quantum mechanics might be a messed up as were early ideas about translating Egyptian hieroglyphics (which we not entirely obvious even after the discovery of he Rosetta Stone)

This is the kind of lecture you watch two or three times; it's so dense.

Honestly this is an easy lecture, but I disagree with his conclusion or it went over my head. I still beleive in the bell theorem, I dont think he changed my mind. He is arguing in a subjective way rather than objective. Bell showed that the type of measurement on A is changing the probability on B. That plainly means measurement S applied on A is effecting the quantume state of particle B eventhough the measurement was done in the future. For me the only logical solution for this question is destiny and complete determination, if you want to keep the speed of causality intact.

Impressive. I like the emphasis on causal structure and the hint of information, disguised as probability. May be worth looking up work of Judea Pearl and Ron Garret too.

The lecture started great, but then he lost me or at least I disagreed with him later on. If measurement on A is effecting the results on B, this does not mean that there is imperfect knowledge that we have not yet grasped.

WOW thankyou for this !

A third option: A measurement reveals neither the quantum state of the measured object nor the state of our knowledge of the object's quantum state. It instead produces a result determined by the entanglement of the measured object with the measurement device. The choice of which measurement to take determines the nature of that measurement device's entanglement with the measured object (and any other entangled objects).

Did you miss the word ' not ' in your comment ?

There are some inaccuracies in this lecture. 1. The "Drug"-Experiment works perfectly well (or not) - it simply depends on the question you ask. If you want to know whether men - compared to women - chose the drug more often, you got a reliable result. If you want to know about the effect of drug-treatment, you of course test the same amount of women and men who TOOK the drug. 2. Quantum entanglement doesn't violate speed of light-limit because there's no information transferred - that's what entanglement is all about. In other words: You can't send signals, because the "two" particles behave like one.

Great arguments from Analogy.

I'm not well-versed in quantum mechanics (at all) but from reading and watching these sorts of lectures and discussions, I thought there was not considered to be any conflict between entanglement producing "spooky action at a distance" and the limitation of the speed of light. Something along the lines of (which Spekkens did mention momentarily) that no actual, useful "information" can be sent in the process. Am I wrong about this? If I'm right, why does Spekkens argue that the entanglement concept (with the confirming results of Bell's) and the limitations of light speed are in "tension" or disagreement?

Excellent information! Misconceptions about quantum physics are perpetuated by misinterpreting statistical representation.

I like the parallel between the search to understand Egyptian hieroglyphs and quantum theory....I'll go so far as to say we have another parallel here....Jean Francois Champollion and Robert Spekkens

More people should know about this channel

One hour, 14 minutes and 36 seconds just to say, "Consider the man who took the wrong approach in translating an ancient language that proved NOT to be successful. Then he took the right approach that DID prove to be successful. Therefore, quantum theory is the wrong approach, even though it's been proven to be successful(for the last 100 years). The right approach is to know what we will know, by calculating the probability of what we will know. I don't know how to calculate that." I wish I knew how to calculate that. I would have calculated the certainty I wouldn't know anything new by watching this video.

GREAT!!!!!!

The good old epistemic vs ontic debate of QE never gets old but why do I get the feeling that 1) the epistemic view proponents are just repackaging (old wine in a new bottle) when stating that spookiness at a distance is just a category mistake and that 2) it is motivated by the fact that philosophers just can't accept the weirdness of indeterminacy and are still trying to impose their classical expectations on quantum reality?

Skip the sudoku analogy and start at 14:00 for quantum mechanics.

In view of Bell’s theorem, Kochen-Specker’s theorem, etc., I think Spekkens‘ idea could only be extended to cover the whole of QM, and not just the Clifford fragments, if at the same time we accept that quantum states are states of knowledge, we acknowledge that the underlying ontological states, which are assumed to be determinate all along, are not physical, so that their properties are not the same as the properties that enter into quantum states. That would fit rather well Kant’s distinction between phenomena and things in themselves. Perhaps it is taking Kant a bit more seriously that is required to make sense of QM.

I'm not sure what you're saying - I understand you saying the whole QM state are states of knowledge while the underlying states are ontological but are you also saying that the ontic states are deterministic? - the pure quantum state seems indeterministic since the collapse of the wave particle to particles is random and we are left with statistical predictions but no causal account Since one is random (collapse of wave to particles) and the other deterministic (the wave itself), we don't really have a deterministic dualism in the way Kant would feel comfortable. One thing I did agree with him was that the epistemic and ontic view are competitors and are not compatible. He is squarely on the epistemic side and would disagree with dualism as an explanation.

The " Spooky action at a Distance " , suggests to me that those sub atomic particle are STILL in the singularity. ( oops , Have I just given the game away ? ) There are some movies, where the Hero/Victim keeps thinking they are Safe ! They even live a full life, have kids, only when they 'die' , do they realize they are STILL in the game and haven't gone anywhere.

A fascinating talk. If quantum state is a category mistake, what happens to classical state (and trajectories and orbits in a phase space) as used in state space models of dynamical systems? I have been trying to study how to model certain cognitive systems using some kind of generalized state space (technically, as objects and morphisms in a star-autonomous category). Spekkens has co-authored an article with Bob Coecke, who writes on both quantum foundations (e.g. Categorical Quantum Mechanics with Samson Abramsky) and cognitive-linguistic models, arguing that some of the mathematical structure of, for example Feynman diagrams and Penrose string diagrams of quantum interactions (not related to string theory) are similar to pregroup grammars as developed by the category theorist Joachim Lambek for modeling natural language. I am not sure how Spekkens work might relate to cognitive systems, but going beyond Bayesian probability could be quite relevant. And his comments about Clifford groups makes me wonder about Clifford algebras, quaternions, the unitary group SU(2), and quantum groups more generally.

Might another way to explain this perceptual/intuitive discrepancy between knowledge/reality be the fields of endeavors? Matter and energy though connected need different tools to categorize, interpret, perceive and intuit. With mathematical frameworks we can bridge those discrepancies and comprehend them using virtual time-space fields of infinite dimensions. Quantum computers might enable us to understand the causation s long before experimental validations.

Have you tried to connect your ideas with the work done by Nichol Furey and Mia Hughes using octonions?

Yeah ,,, I had to rewind a few times, because I stopped listening. - It's his voice. He needs a narrator if ever he makes a documentary .

Bell's inequality is about hidden reality, that depends on something we still do not know. Heisenberg's uncertainty principle says knowledge of position hides knowledge of momentum. So with one measurement we know 50% about position and in another setting we know 50% momentum but not of the same phenomenon or the same set up. However, QM's abstractness does not prevent us from appreciating how the SINGLE probability wave function governs all phenomenon as quantum process with certainty ( quantum physics is better formulated than classical).

I think "Spooky action at a distance" really is a result of the possibility that changes for elementary particles happens in another dimension , the 6th to be exact ! This dimension is (as I understand) the "RIFT"-dimension which separates matter/antimatter !

This was a pretty good talk. Why were so many people falling asleep?

Following the thought ... if the problem is join 3D (the positions) with 2D (the knowledge) is a geometry problem. So, if we have a sphere we need PI. Add PI to PSI. Dont have any clue of the outcome but its only a thought....

What has statistics to do with time-space? If relativity suggests that there is a top speed which is constant while we have a an apparent artifact that disapproves shouldn't we look at sub spaces that introduce lower-dimensional systems which facilitate the interactions(not transactions since if there were any those should be measurable) and introduce the variation observed compared to effective reduction of complexity(looking from the amount of knowledge of the system) combined with increase in the complexity in regards of the mathematical description that is supposed to account for the knowledge we loose?

consensus will require making things simpler, not more complicated :)

Unfortunately, in the summary at 1:04:00 he totally misses the point. It is the *data* (in particular the fact that it contradicts Bell's inequality) that leads to the conclusion that there is a "spooky action". You do not need quantum theory to (derive Bell's inequality, look at the data, and) conclude this. Therefore, the problem cannot be solved by changing the "interpretation of the quantum state", because you do not even need to know what this is to "see" the spooky action. Interestingly, he uses a similar kind of fallacy as described earlier in the talk. The facts are: (1) The assumptions that information cannot travel faster than light and that the (probability distribution for the) outcome of a measurement is a property of the object on which the measurement is carried out implies Bell's inequality. (2) The experimental data contradicts Bell's inequality. (3) The experimental data is predicted correctly by quantum theory. (2) implies that at least one assumption made in (1) is false, which implies that either infomation travels faster than light or something even more spooky influences the choice of the operator which measurement to make. None of these arguments uses or relies on quantum theory. It could have been derived in 1900 if someone made such an experiment (for whatever reason). (3) is logically completely independent of (1) and (2). At 49:00 (after distracting for 10min with this Clifford stuff and his baby) he got it almost right, but still missed the cruicial point: Bell has shown that the if you assume the causal structure as shown in the graph on the right, then the statistical data shown in the table on the left is impossible. Period. Again, no quantum theory here. His statement is logically correct, but the additional assumption "… and assume that the quantum state blah blah…" suggest that the statement becomes wrong if you drop this. It doesn't. And therefore, even if you replace quantum theory by something complete different, the spooky action will not go away. It might become less spooky within a better theory, but this theory then has to modify *other* theories as well, namely those that are used in (1), e.g. relativity. To prove exactly this was the contribution of Bell. The Bohr-Einstein debate would have proceeded very differently if Bell did it twenty years earlier.

Oh my God! Once you hear him say uh you can't stop hearing it uh it's uh like uh every word uh

Excellent. Maybe some day they will figure out that quantum computers are not proven by QM. The Born rule is metaphysical fluff and QM just gives the expectations of observables. We use probability in QM for the same reason we use it in classical physics. It's actually quite easy to generalize both and in a useful way. The inability to see what Spekkens is saying is why we have nutty many-worlds interpretations becoming popular. These people are making basic mistakes in the theory. However, there is nothing really new here. This doesn't really contradict Copenhagen. People have just piled non-sense on top of it.

So many different QM interpretations. And maybe it is an yet unknown interpretation which holds the correct explanation of QM.

On one hand, it's good that someone is looking into this. On the other hand, he never gave any defense of what he's doing to probability theory. The calculus of probabilities is one of the most elegant applications of mathematics to the real world ever invented - trying to explain quantum mechanics by carving a huge swatch of theoretically ugly exceptions through it is really unsatisfying to me.

The underlying nature is not changing. It is how we categorize what is a particle and what is a wave that makes it seem as if reality has changed. Everything is waves / vibrations. A particle is just a "chunk" of the vibrations. Quantum field theory is the thing you should look into. Apparently the only reason we hear about particles is because they think it is too hard to describe to a popular audience how everything is vibrations of various fields.

yes, but I thought hidden parameters were fine with Bell as long as you accept non-local distribution of such positive information (see e.g. Bohm's pilot wave). The parameters could be just not with the particles at the detectors but in some abstract account independent of space time - or at least correlated with spacetime in a "fine-tuned" way that does not allow for signalling faster than light. According to Spekkens here, the wave function is about a description of knowledge from a global perspective, and that can change globally like Bayesian probability updates when we learn about new measurements - but he seems to use some other formalism (the star thingies etc). Let's just let him do his thing - we'll see if he comes up with something that convinces the world - and he has a point that only a few are looking into these matters...

The Simpson's "Paradox" is flawed in the manner that the number of women and men that take the drug are not equal in actual numbers. You're ignoring the weighting of the function with this example. It only proves which gender is more likely to take the drug. If weighted correctly, it correlates to not taking the drug provides a 6:7 ratio of recovery for men and a 2:3 ratio for women. There's no paradox there because the dataset is misconstrued. If averaged, for every 3 recoveries with taking the drug, there would be 7 recoveries from people who did not take the drug.

A beautiful mind always simplifies and the speaker categorizes Quantum Cubits as Seduco solutions . In the quantum state matter takes on a varying forms due to the lack of forces one would find in larger matter and the mistake is that we are quantifying and categorizing results prematurely. What I am trying to say is that the external force becomes influencers as to what happens in quantum. WE MUST TURN ALL TRADITIONAL THINKING ON ITS HEAD AND RATHER MEASURE THE FORCES APPLIED ON THE QUANTUM RATHER THAN MEASURING THE QUANTUM

Every measurement made in the Standard Model of Physics and Astronomy is a "discovery" of Entangled Quantum Information in which the reciprocal wave-particle Fields Modulation Mechanism relationship is inferred. The "One Electron" theory is a practical Physicists interpretation of a modulation-demodulation integration of Superspin at the Singularity Vanishing Point, and it's complimentary mathematical conjecture of Banach-Tarski, applies to more specific dimensional interpretation. The combined quantum chemistry phase state of dualistic timing is the subject of Quantum Computation and the cause-effect values of Temporal Superposition.
