Even though China gave up on most communist ambitions post-Dheng

No they haven’t.

Quantum nonlocality really is a misnomer. Nothing is nonlocal about it. We know from the No-communication Theorem that there is no physical interaction you could carry out with one particle in an entangled pair that would affect the state of the other particle, and we know it is compatible with special relativity, which is a fundamentally local theory, as such a unification of the two is how we get quantum field theory.

“Local realism” is also a nonsensical term. There is no agreed upon rigorous definition of “realism” and its introduction to the scientific literature has only served to confuse the discussion and promote quantum mysticism because people think because Bell’s theorem supposedly shows that “local realism” is false that you there have to choose between locality or realism, but not both, and since we know the universe is local, we have to conclude there is no objective reality, devolving into mysticism and idealism.

This isn’t just a problem in popsci articles but even in published scientific literature. This “local realism” hogwash has caused even otherwise respectable physics to publish nonsense about how reality doesn’t exist. The term “realism” is never used in Bell’s theorem and has tn relevance to it. Bell’s theorem is about local hidden variable theories, and it is complete nonsense to conflate hidden variables with “realism” as if your only choices are to believe the reality is deterministic or to deny reality even exists! What kind of options are those? What about a third option that reality exists and it is just nondeterministic?

What Bell’s theorem shows is that quantum mechanics cannot be replaced with a local hidden variable theory, and since we know the universe is local, that means it cannot be replaced with a hidden variable theory. It forces us to accept nondeterminism, it doesn’t force us to deny reality, nor does it prove there is nonlocality.

It can, under certain conditions, contain information about things at a distance, but a function is not a physical entity and its reduction is not a physical process, so none of this reflects anything superluminal actually going on in physical reality.
