The emperor has no nonlocality

摘要

The Einstein–Podolsky–Rosen (EPR) experiment and certain predictions of quantum mechanics in theoretical and experimental forms are sometimes described as exhibiting nonlocal action. We describe here an interpretation of one oft-discussed EPR experiment with a locally realistic model. We demonstrate a consistent description based on probabilistic measurement for Mermin and Aspect EPR setups, and show how Bell’s theorem applies. Quantum nonlocality is shown to be an interpretation dependent on deterministic measurement and vanishes when a treatment of probabilistic measurement and relevant information theory is included.
