The 2022 Nobel Prize in Physics has been awarded to Alain Aspect, John Clauser and Anton Zeilinger for their groundbreaking work in Quantum Entanglement. Here is a brief visual summary of the essential physics.
z He spends the first couple of minutes arguing that Newtonian mechanics is deterministic, white quantum mechanics is not. I dont think this has anything to do with the Bell test work.
At 4:50, he says that a measurement on one particle can have an instantaneous effect on a distant particle. This is false. Any experimental proof of this would have immediate Nobel prizes.
He says that Einstein wrote a 1935 paper arguing that QM cannot be the whole story. And this Nobel prize winning work addresses that. But Greene does not explain whether the work proved Einstein right or wrong.
Einstein implied that he preferred a local hidden variable theory. The Bell test experiments prove that impossible, so they prove Einstein wrong. Greene says Einstein also wanted a non-probabilistic theory, although that is not so clear from the paper.
I guess Greene is trying to say that Einstein rejected mainstream thinking in 1935, and this prize is for work showing that the mainstream thinking was correct.
But dozens of Nobel prizes have been given for quantum mechanics, so why give another one now?
Greene answer seems to be that the prize work proved action-at-a-distance. It does not.
