Abstract: The Bell’s inequality is a strong criterion to distinguish classical and quantum mechanical aspects of reality. Its violation is the net effect of the existence of non-locality in systems, an advantage for quantum mechanics over… read more here.

Abstract: We initiate the study of the nonlocal correlations in generic asymmetric quantum networks in a star configuration. Therein, the diverse unrelated sources can emit either partially or maximally entangled states, while the observers employ varying… read more here.

DOI: 10.1103/physreva.110.052429
Abstract: Quantum information theory explores numerous properties that surpass classical paradigms, offering novel applications and benefits. Among these properties, negative conditional von Neumann entropy (CVNE) is particularly significant in entangled quantum systems, serving as an indicator… read more here.

DOI: 10.1142/s0219749922500113
Abstract: Using the Hilbert–Schmidt (HS) decomposition we suggest new possible choices of Bell operators and entanglement witnesses (EWs) for [Formula: see text] ([Formula: see text]) qubits systems for (full/bi) separability. The latter give upper bounds for… read more here.
