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…
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…
Detecting non-locality in multipartite quantum systems with two-body correlation functions
J. Tura, R. Augusiak, A. B. Sainz +3
Bell inequalities define experimentally observable quantities to detect non-locality. In general, they involve correlation functions of all the parties. Unfortunately, these measur…
Checking the optimality of entanglement witnesses: an application to structural physical approximations
R. Augusiak, J. Bae, J. Tura +1
In 2008, the conjecture that structural physical approximations to optimal entanglement witnesses are separable states (in general unnormalized) was posed. In an attempt to disprov…
