Is the Moon there when no one is looking?

Is she spinning clockwise or counterclockwise?

Quantum entanglement is an illusion, not reality!

Here is perhaps the simplest possible explanation of the results presented in my RSOS paper:

Let A(a, h) and B(b, h) be the results observed independently by Alice and Bob in their EPR-Bohm type experiment. Here h is a randomness shared between Alice and Bob and a and b are their freely chosen experimental parameters. Then, Bell correctly claimed that the correlation E(a, b) = << A(a, h) B(b, h) >> between their results cannot exceed the linear limit. This claim is, in fact, correct, regardless of what one thinks of the Bell inequalities. But Bell’s oversight in his claim is that the randomness h is not the only thing that is shared between Alice and Bob. What they also share, inevitably, are the algebraic, geometrical and topological properties of the physical space within which they are confined to perform their experiment. Once this is understood and the properties of the physical space are taken into account correctly, the correlation between the results A(a, h) and B(b, h) is inevitably equal to E(a, b) = -cos(a, b).

And here is what talented experimental physicists with a lot of funding but little or no intelligence believe: https://journals.aps.org/prl/abstract/1 ... 121.220404

In my view, such "violations" of any Bell-type inequalities, in any actual experiment, simply mean a confirmation of quantum mechanical predictions, not a disproof of locality or realism.

I have long predicted such "violations" of Bell inequalities for macroscopic systems (cf. this paper) because they are simply a manifestation of the algebraic, geometrical and topological properties of the physical space we live in, not because of a failure of local-realism. Bell inequalities would be exceeded for any system, classical or quantum, microscopic or macroscopic.

Over the past few decades, experimental tests of Bell-type inequalities have been at the forefront of understanding quantum mechanics and its implications. These strong bounds on specific measurements on a physical system originate from some of the most fundamental concepts of classical physics—in particular that properties of an object are well-defined independent of measurements (realism) and only affected by local interactions (locality). The violation of these bounds unambiguously shows that the measured system does not behave classically, void of any assumption on the validity of quantum theory. It has also found applications in quantum technologies for certifying the suitability of devices for generating quantum randomness, distributing secret keys and for quantum computing. Here we report on the violation of a Bell inequality involving a massive, macroscopic mechanical system. We create light-matter entanglement between the vibrational motion of two silicon optomechanical oscillators, each comprising approximately 10^10 atoms, and two optical modes. This state allows us to violate a Bell inequality by more than 4 standard deviations, directly confirming the nonclassical behavior of our optomechanical system under the fair sampling assumption.

In my view, such "violations" of any Bell-type inequalities, in any actual experiment, simply mean a confirmation of quantum mechanical predictions, not a disproof of locality or realism.

The PRL authors write "... we have demonstrated the violation of a Bell-type inequality using massive (around 10^10 atoms), macroscopic optomechanical devices, thereby verifying the nonclassicality of their state without the need for a quantum description of our experiment." https://journals.aps.org/prl/abstract/1 ... 121.220404

But isn't that what I have been saying for the past eleven years? https://www.academia.edu/24765800/Propo ... ls_Theorem

I have written up an explicit proof of the equation (2.40) --- or equivalently of the equation (2.59) of my RSOS paper, because its validity had been aggressively questioned by Richard D. Gill for several months with intentions to have the paper retracted. The proof is in the form of the following self-contained note: http://einstein-physics.org/wp-content/ ... tonion.pdf

The key phrase by the authors here is the following:

"... without the need for a quantum description of our experiment."

What this means is that we have an experimental proof --- published in PRL --- that Bell-type inequalities can be "violated" by purely classical, macroscopic systems!!!

But of course they can be: https://link.springer.com/article/10.10 ... 014-2412-2. That has long been predicted by my local-realistic model for the quantum correlations.

It has been claimed elsewhere on the Internet that by “nonclassicality” the authors of the above PRL paper mean “violation of local realism.”; and they do seem to support this orthodox interpretation by providing a quantum description of their massive, macroscopic, mechanical system. I very much doubt that their paper would have been accepted by PRL if they didn’t.

However, to their credit, the key phrase also used by the PRL authors to describe their experiment is the following: ``... without the need for a quantum description of our experiment."

Thus we have an experimental proof that Bell-type inequalities can be violated also by purely classical, massive, macroscopic, mechanical systems without requiring quantum quackery.

In addition to what I have written above, note well that "violations" of Bell inequalities have absolutely nothing to do with Einstein's local realism: https://arxiv.org/abs/1704.02876.
