Abstract

Can quantum correlations of the singlet state be produced by two separate subsystems which have interacted in the past but do not communicate? We show that, using a locally causal realist model of the Einstein-Podolsky-Rosen-Bohm experiment, the answer is affirmative if coincidence in time is used to decide which detection events are stemming from a single two-particle system, the criterion employed in all experimental realizations of the Einstein-Podolsky-Rosen-Bohm gedanken experiment.
