DOI: 10.1088/1367-2630/aaff2d
Abstract: Local measurements acting on entangled quantum states give rise to a rich correlation structure in the multipartite scenario. We introduce a versatile technique to build families of Bell inequalities witnessing different notions of multipartite nonlocality… read more here.

DOI: 10.1088/1367-2630/ab4d9f
Abstract: In device-independent quantum information processing Bell inequalities are not only used as detectors of nonlocality, but also as certificates of relevant quantum properties. In order for these certificates to work, one very often needs Bell… read more here.

DOI: 10.1088/1402-4896/abdd56
Abstract: At first sight, the use of an everywhere positive Wigner function as a probability density to perform stochastic simulations in quantum optics seems equivalent to the introduction of local hidden variables, thus preventing any violation… read more here.

DOI: 10.1103/physreva.100.022114
Abstract: A Bell inequality is a constraint on a set of correlations whose violation can be used to certify non-locality. They are instrumental for device-independent tasks such as key distribution or randomness expansion. In this work… read more here.

DOI: 10.1103/physreva.98.022133
Abstract: Two overlapping bipartite binary input Bell inequalities cannot be simultaneously violated as this would contradict the usual no-signalling principle. This property is known as monogamy of Bell inequality violations and generally Bell monogamy relations refer… read more here.

DOI: 10.1103/physrevlett.124.020402
Abstract: Bell inequalities constitute a key tool in quantum information theory: they not only allow one to reveal nonlocality in composite quantum systems, but, more importantly, they can be used to certify relevant properties thereof. We… read more here.

DOI: 10.1109/access.2021.3063744
Abstract: Bell nonlocality of quantum states is an important resource in quantum information and then has various applications. It is usually detected by the violation of some Bell’s inequalities and the all-versus-nothing test. In the present… read more here.
