Proofs of nonlocality without inequalities revisited
GianCarlo Ghirardi, Luca Marinatto
We discuss critically the so-called nonlocality without inequalities proofs for bipartite quantum states, we generalize them and we analyze their relation with the Clauser-Horne in…
A critical analysis of Popper's experiment
GianCarlo Ghirardi, Luca Marinatto, Francesco de Stefano
An experiment which could decide against the Copenhagen interpretation of quantum mechanics has been proposed by K. Popper and, subsequently, it has been criticized by M.J. Collett…
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…
Identical particles and entanglement
GianCarlo Ghirardi, Luca Marinatto
We review two general criteria for deciding whether a pure bipartite quantum state describing a system of two identical particles is entangled or not. The first one considers the p…
