Critical visibility for N-particle Greenberger-Horne-Zeilinger correlations to violate local realism
A sequence of Bell inequalities for N -particle systems, which involve three settings of each of the local measuring apparatuses, is derived. For GHZ states, quantum mechanics violates these inequalities by factors exponentially growing with N . The threshold visibilities of the multiparticle sinusoidal interference fringes, for which local realistic theories are ruled out, decrease as (2/3)N ....

A sequence of Bell inequalities for N-particle systems, which involve three settings of each of the local measuring apparatuses, is derived. For GHZ states, quantum mechanics violates these inequalities by factors exponentially growing with N.

متن کاملNMR Greenberger–Horne–Zeilinger states
We describe the creation of a Greenberger–Horne–Zeilinger state of the form (|000〉+ |111〉)/√2 (three maximally entangled quantum bits) using nuclear magnetic resonance. We have successfully carried out the experiment using the proton and carbon spins of trichloroethylene, and confirmed the result using state tomography. We have thus extended the space of entangled quantum states explored system...
متن کاملEntanglement distillation from Greenberger-Horne-Zeilinger shares
We study the problem of converting a product of Greenberger-HorneZeilinger (GHZ) states shared by subsets of several parties in an arbitrary way into GHZ states shared by every party. Our result is that if SLOCC transformations are allowed, then the best asymptotic rate is the minimum of bipartite log-ranks of the initial state. This generalizes a result by Strassen on the asymptotic subrank of...
متن کاملGreenberger-Horne-Zeilinger paradoxes for many qudits.
We construct Greenberger-Horne-Zeilinger (GHZ) contradictions for three or more parties sharing an entangled state, the dimension of each subsystem being an even integer d. The simplest example that goes beyond the standard GHZ paradox (three qubits) involves five ququats (d=4). We then examine the criteria that a GHZ paradox must satisfy in order to be genuinely M partite and d dimensional.
