Another Look at Bell's Inequalities and Quantum Mechanics

Abstract

Feynman's path integrals provide a hidden variable description of quantum mechanics (and quantum field theories). The expectation values defined through path integrals obey Bell's inequalities in Euclidean time, but not in Minkowski time. This observation allows us to pinpoint the origin of violation of Bell's inequalities in quantum mechanics. % This article is not precise enough for mathematicians and not vague % enough for philosophers, but it should be interesting for physicists. % Contributed to the XVI International Symposium on Lepton-Photon % Interactions, Cornell University, August 10-15, 1993.
