Hardy's proof of nonlocality in the presence of noise
GianCarlo Ghirardi, Luca Marinatto
We extend the validity of Hardy's nonlocality without inequalities proof to cover the case of special one-parameter classes of non-pure statistical operators. These mixed states ar…

Hardy's criterion of nonlocality for mixed states
GianCarlo Ghirardi, Luca Marinatto
We generalize Hardy's proof of nonlocality to the case of bipartite mixed statistical operators, and we exhibit a necessary condition which has to be satisfied by any given mixed s…

Greenberger-Horne-Zeilinger argument of nonlocality without inequalities for mixed states
GianCarlo Ghirardi, Luca Marinatto
We generalize the Greenberger-Horne-Zeilinger nonlocality without inequalities argument to cover the case of arbitrary mixed statistical operators associated to three-qubits quantu…
