    "abstract": "In this paper we provide a simple proof of the fact that for a system of two\nspin-1/2 particles, and for a choice of observables, there is a unique state\nwhich shows Hardy-type nonlocality. Moreover, an explicit expression for the\nprobability that an ensemble of particle pairs prepared in such a state\nexhibits a Hardy-type nonlocality contradiction is given in terms of two\nindependent parameters related to the observables involved. Incidentally, a\nwrong statement expressed in Mermin\u0027s proof of the converse [N.D. Mermin, Am.\nJ. Phys. 62, 880 (1994)] is pointed out.",
