A simple proof of the converse of Hardy's theorem
Abstract
In this paper we provide a simple proof of the fact that for a system of two spin1/2 particles, and for a choice of observables, there is a unique state which shows Hardytype nonlocality. Moreover, an explicit expression for the probability that an ensemble of particle pairs prepared in such a state exhibits a Hardytype nonlocality contradiction is given in terms of two independent parameters related to the observables involved. Incidentally, a wrong statement expressed in Mermin's proof of the converse [N.D. Mermin, Am. J. Phys. 62, 880 (1994)] is pointed out.
