The definition of multipartite nonlocality
Jean-Daniel Bancal, Jonathan Barrett, Nicolas Gisin +1
In a multipartite setting, it is possible to distinguish quantum states that are genuinely -way entangled from those that are separable with respect to some bipartition. Similar…
Quantum nonlocality based on finite-speed causal influences leads to superluminal signaling
Jean-Daniel Bancal, Stefano Pironio, Antonio Acin +3
The experimental violation of Bell inequalities using spacelike separated measurements precludes the explanation of quantum correlations through causal influences propagating at su…
Device-independent witnesses of genuine multipartite entanglement
Jean-Daniel Bancal, Nicolas Gisin, Yeong-Cherng Liang +1
We consider the problem of determining whether genuine multipartite entanglement was produced in an experiment, without relying on a characterization of the systems observed or of…
Extremal correlations of the tripartite no-signaling polytope
Stefano Pironio, Jean-Daniel Bancal, Valerio Scarani
The no-signaling polytope associated to a Bell scenario with three parties, two inputs, and two outputs is found to have 53856 extremal points, belonging to 46 inequivalent classes…
Various quantum nonlocality tests with a simple 2-photon entanglement source
Enrico Pomarico, Jean-Daniel Bancal, Bruno Sanguinetti +2
Nonlocality is a fascinating and counterintuitive aspect of Nature, revealed by the violation of a Bell inequality. The standard and easiest configuration in which Bell inequalitie…
