Joint Distributions and Quantum Nonlocal Models

Blog Article

A standard result in quantum mechanics is this: if two observables are commuting corgi pup knife then they have a classical joint distribution in every state.A converse is demonstrated here: If a classical joint distribution for the pair agrees with standard quantum facts, then the observables must commute.This has army meritorious civilian service medal consequences for some historical and recent quantum nonlocal models: they are analytically disallowed without the need for experiment, as they imply that all local observables must commute among themselves.
