Interpretation of the Einstein-Podolsky-Rosen Effect in Terms of a Generalized Causality

Part of the Physics of Atoms and Molecules book series (PAMO)


After many years of discussion of the Einstein-Podolsky-Rosen (EPR) effect (and of similar effects which appear in the consideration of a pair of correlated systems which were once coupled with one another and subsequently separated), a majority of physicists have come to the conclusion that the quantum phenomena, revealed by measurements performed on such systems, exhibit a manifestly nonlocal character, even on a macroscopic scale. A measurement performed on one of two widely-separated systems affects the other system—as it seems—instantaneously, or in other words, information about the result of the measurement appears to propagate with superluminal velocity, in apparent violation of the laws of relativity and causality. Quantum physicists explain this situation by pointing out that quantum phenomena are characterized by a certain “discreteness” and integrity due to the existence of the quantum-of-action h. Some of them even believe that quantum phenomena cannot be completely accommodated within the realm of space-time and, therefore, surpass its framework.
