Interpretation of the superposition principle and locality loophole in Bell experiments

Abstract

A connection is revealed between the superposition principle and locality. A self consistent interpretation of the superposition principle is put forth, from which it is shown that quantum mechanics may be a local statistical theory. Then it is shown how Bell experiments can be satisfactorily explained by assuming local nature for entangled particles, i.e., the violation of Bell inequality cannot distinguish between locality and nonlocality, which is referred to as locality loophole. Moreover, existing experimental results are presented indicating locality in quantum mechanics and new experiments are proposed so that the locality loophole may be closed.
