Translationally invariant multipartite Bell inequalities involving only two-body correlators
J. Tura, A. B. Sainz, T. Vértesi +3
Bell inequalities are natural tools that allow one to certify the presence of nonlocality in quantum systems. The known constructions of multipartite Bell inequalities contain, how…
Exploring the Local Orthogonality Principle
A. B. Sainz, T. Fritz, R. Augusiak +4
Nonlocality is arguably one of the most fundamental and counterintuitive aspects of quantum theory. Nonlocal correlations could, however, be even more nonlocal than quantum theory…
Detecting nonlocality of noisy multipartite states with the CHSH inequality
Rafael Chaves, Antonio Acín, Leandro Aolita +1
The Clauser-Horne-Shimony-Holt inequality was originally proposed as a Bell inequality to detect nonlocality in bipartite systems. However, it can also be used to certify the nonlo…
Nonlocality in sequential correlation scenarios
Rodrigo Gallego, Lars Erik Würflinger, Rafael Chaves +2
As first shown by Popescu [S. Popescu, Phys. Rev. Lett. 74, 2619 (1995)], some quantum states only reveal their nonlocality when subjected to a sequence of measurements while givin…
Elemental and tight monogamy relations in nonsignalling theories
R. Augusiak, M. Demianowicz, M. Pawłowski +2
Physical principles constrain the way nonlocal correlations can be distributed among distant parties. These constraints are usually expressed by monogamy relations that bound the a…
Device-independent quantum key distribution with spin-coupled cavities
Alejandro Máttar, Jonatan Bohr Brask, Antonio Acín
Device-independent quantum key distribution (DIQKD) guarantees the security of a shared key without any assumptions on the apparatus used, provided that the observed data violate a…
