Abstract

Much work has been done on comparing quantum to classical (local realistic) theories [1] and researchers have considered whether quantum theory can be reproduced by any conceivable local realistic theory. It has been shown that no such theory can mimic certain quantum theoretic correlations, such as those in Bell’s theorem. Much work done in this area involves idealized microscopic systems and it is of interest to see whether any intrinsically quantum phenomena exist for experimentally realizable macroscopic systems. It is of interest, obviously, for actual experiments but also to probe the nature of the classical limit of quantum theory.
