At least, according to this paper - http://arxiv.org/ftp/quant-ph/papers/0206/0206190.pdf - nonlocality isn't real in QM.

DrChinese said:The hypothesis is overreaching - that you can somehow "disprove" nonlocality.
But as is mentioned, the experimental support is a joke. QM properly predicts the actual results of all spacelike separated experiments. You can call that proof of nonlocality or not, depending on your interpretation. For the experiment to mean what he says it does, it would need to contradict QM.
Non-locality in Quantum Mechanics refers to the phenomenon where two particles that have interacted in the past can instantaneously affect each other's behavior, even when they are separated by a large distance. This was initially thought to violate the principles of causality and relativity.
The main evidence for non-locality in Quantum Mechanics comes from the famous EPR paradox proposed by Einstein, Podolsky, and Rosen in 1935. This paradox demonstrated that if Quantum Mechanics is correct, then non-locality must exist. Furthermore, numerous experiments, such as the Bell test experiments, have also shown evidence for non-locality.
Recent studies and experiments have shown that non-locality in Quantum Mechanics is not a violation of causality or relativity. Instead, it is a consequence of the way particles are entangled at the quantum level. This means that non-locality is a fundamental aspect of the quantum world and is not in conflict with our current understanding of physics.
No, non-locality cannot be used for faster-than-light communication. While it may seem that information can be transmitted instantaneously through non-locality, it is not possible to control or manipulate the behavior of entangled particles. Thus, it is not possible to use non-locality for communication purposes.
This has significant implications for our understanding of the universe and the nature of reality. It suggests that the laws of physics are local, meaning that events in one location cannot instantaneously affect events in another location. This also has implications for our understanding of time and space, as well as the concept of causality in the quantum world.
