DOI: 10.1007/s10773-021-04788-y
Abstract: Quantum nonlocality plays an important role in quantum information and quantum communication. Different from local realism, nonlocality means that multiple bodies can affect each other instantaneously regardless of the distance. The more the systems, the… read more here.

DOI: 10.1007/s11128-024-04638-w
Abstract: Bell nonlocality is a valuable resource in quantum information processing tasks. Scientists are interested in whether a single entangled state can generate a long sequence of nonlocal correlations. Previous work has accomplished sequential tripartite nonlocality… read more here.

DOI: 10.1021/acs.jpcc.6b12546
Abstract: With the self-consistent mean-field method in the framework of full-wave nonlocal scattering theory, we theoretically investigate the optical bistability in a nonlocal metallic nanocylinder coated with Kerr-type nonlinear shell. A nonlocality enhanced Fano profile is… read more here.

DOI: 10.1038/s41534-020-00305-x
Abstract: Characterizing quantum nonlocality in networks is a challenging, but important problem. Using quantum sources one can achieve distributions which are unattainable classically. A key point in investigations is to decide whether an observed probability distribution… read more here.

DOI: 10.1088/1402-4896/ad5fc2
Abstract: Entanglement is necessary but not sufficient to demonstrate nonlocality as there exist local entangled states which do not violate any Bell inequality. In recent years, the activation of nonlocality (known as hidden nonlocality) by using… read more here.

DOI: 10.1088/1402-4896/ae098c
Abstract: We investigate the dynamics of quantum correlations in bipartite systems initially prepared in a squeezed state, comparing closed-system unitary evolution under the Schrödinger equation with open-system dynamics governed by the Caldeira-Leggett master equation in the… read more here.

Abstract: Recently, Halder et al (2019 Phys. Rev. Lett. 122 040403) proposed the concept of strong nonlocality without entanglement: an orthogonal set of fully product states in multipartite quantum systems that is locally irreducible for every… read more here.

DOI: 10.1103/p5pd-749f
Abstract: Heisenberg's uncertainty principle, coherence, and Bell nonlocality have been individually examined through many experiments. In this Letter, we systematically characterize all of this quantumness in a unified manner. We first construct universal uncertainty relations to… read more here.

DOI: 10.1103/physreva.100.012102
Abstract: Via nonlocality distillation, a number of copies of a given nonlocal correlation can be turned into a new correlation displaying a higher degree of nonlocality. Apart from its clear relevance in situations where nonlocality is… read more here.

Abstract: Bell's theorem shows that correlations created by a single entangled quantum state cannot be reproduced classically, in a local way. Such correlations are called \emph{Nonlocal}. The notion of nonlocality is extended to \emph{Network Nonlocality} by… read more here.
