Multiparticle interference, Greenberger-Horne-Zeilinger entanglement, and full counting statistics.

چکیده
We investigate the quantum transport in a generalized N-particle Hanbury Brown-Twiss setup enclosing magnetic flux, and demonstrate that the Nth-order cumulant of current cross correlations exhibits Aharonov-Bohm oscillations, while there is no such oscillation in all the lower-order cumulants. The multiparticle interference results from the orbital Greenberger-Horne-Zeilinger entanglement of N indistinguishable particles. For sufficiently strong Aharonov-Bohm oscillations the generalized Bell inequalities may be violated, proving the N-particle quantum nonlocality.

متن کاملNecessary and sufficient condition for Greenberger-Horne-Zeilinger diagonal states to be full N-partite entanglement
We show that any N -qubit state which is diagonal in the Greenberger-HorneZeilinger basis is full N -qubit entangled state if and only if no partial transpose of the multiqubit state is positive with respect to any partition.
متن کاملEntanglement classification of relaxed Greenberger-Horne-Zeilinger symmetric states
In this paper we analyze entanglement classification of relaxed Greenberger-HorneZeilinger-symmetric states ρES , which is parametrized by four real parameters x, y1, y2 and y3. The condition for separable states of ρES is analytically derived. The higher classes such as bi-separable, W, and Greenberger-Horne-Zeilinger classes are roughly classified by making use of the class-specific optimal w...
متن کاملCritical 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 ....
