Abstract

Even though quantum mechanics does not allow two experimenters to exchange information acausally, quantum mechanics does allow the responses of independent detectors to be more strongly correlated titan allowed in a classical world in which the response of a detector is determined solely by the causal flow of signals from the transmitters to the detectors. Since the original proposals of Bell for experiments that could display this incompatibility between quantum mechanics and the classical world view, a variety of new proposals have been pul forward and considerable progress has been made in exploring the extent of the incompatibility.
