Tripartite realism-based quantum nonlocality

Revealing Hidden Genuine Tripartite Nonlocality

Nonlocal correlations arising from measurements on tripartite entangled states can be classified into two groups, one genuinely 3−way nonlocal and other local with respect to some bipartition. Still, whether a genuinely tripartite entangled quantum state can exhibit genuine 3−way nonlocality, remains a challenging problem so far as measurement context is concerned. Here we introduce a novel app...

Relativistic Nonlocality Quantum Mechanics and Local Realism in impact series experiments

Experiments in which one of the photons impacts successively at two beam-splitters are described in terms of Quantum Mechanics (QM) and Relativistic Nonlocality (RNL). It argued that: (1) according to RNL first order interferences forbid entanglement, and on the basis of this a new experimental test of local realism is proposed; (2) the conventional superposition principle leads to superluminal...

Quantum Physics: A Case for Anti-Realism?

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 ...

Quantum Nonlocality and Inseparability

wK = 1. A necessary condition for separability is derived and is shown to be more sensitive than Bell’s inequality for detecting quantum inseparability. Moreover, collective tests of Bell’s inequality (namely, tests that involve several composite systems simultaneously) may sometimes lead to a violation of Bell’s inequality, even if the latter is satisfied when each composite system is tested s...
