Three-particle entanglement versus three-particle nonlocality

Three-particle GHZ correlations without nonlocality

The formalism employing local complex amplitudes that resolved the Einstein-Podolsky-Rosen puzzle (C. S. Unnikrishnan, quant-ph/0001112) is applied to the three-particle GHZ correlations. We show that the GHZ quantum correlations can be reproduced without nonlocality. We have recently shown that quantum correlations can be reproduced starting from local probability amplitudes, by calculating th...

Three particle Hyper Entanglement: Teleportation and Quantum Key Distribution

Entanglement acts as an important resource for quantum information and communication. With entanglement between two quantum bits, protocols have been demonstrated for teleporting an unknown qubit [1], denser coding of information [2] and secure communication [3]. An arbitrary qubit can be teleported from one particle to another, irrespective of the distance, with the use of an entangled pair of...

Three-Particle Azimuthal Correlations

Two-particle azimuthal correlations in central Au+Au collisional at RHIC have revealed a broadened away-side structure, with respect to perpherial Au+Au, pp, and d+Au. This could be explained by different physics mechanisms such as: large angle gluon radiation, deflected jets, Ĉerenkov gluon radiation, and conical flow generated by hydrodynamic shock-waves. We can discriminate the scenarios wit...

Tripartite entanglement versus tripartite nonlocality in three-qubit Greenberger-Horne-Zeilinger-class states.

We analyze the relationship between tripartite entanglement and genuine tripartite nonlocality for three-qubit pure states in the Greenberger-Horne-Zeilinger class. We consider a family of states known as the generalized Greenberger-Horne-Zeilinger states and derive an analytical expression relating the three-tangle, which quantifies tripartite entanglement, to the Svetlichny inequality, which ...
