Effects of topological boundary conditions on Bell nonlocality
Physical Review ABell nonlocality is the resource that enables device-independent quantum information processing tasks. It is revealed through the violation of so-called Bell inequalities, indicating that the observed correlations cannot be reproduced by any local hidden variable model.

Statistical link between Bell nonlocality and uncertainty relations [PDF]
Bell nonlocality and uncertainty relations are distinct features of quantum theory from classical physics. Bell nonlocality concerns the correlation strength among local observables on different quantum particles, whereas the uncertainty relations set ...

Bell Nonlocality in Quantum Theory
, 2019 Abstract All the examples of nonlocality that we know are accurately described within quantum theory. This chapter presents the study of CHSH and some systematic results. In particular, we learn that separable states can only give rise to local behaviors, while pure entangled states are nonlocal resources.

Fermionic steering is not nonlocal in the background of dilaton black hole
European Physical Journal C: Particles and FieldsWe study the redistribution of the fermionic steering and the relation among fermionic Bell nonlocality, steering, and entanglement in the background of the Garfinkle–Horowitz–Strominger dilaton black hole.

Quantum steering and coherence evolution of two atoms under noisy environments
Results in PhysicsBy considering two kinds of non-Markovian (NM) environments, the dynamical behavior of quantum steering, Bell nonlocality and coherence of a system of two atoms initially immersed in a vacuum has been studied.

The quantum world is not built up from correlations [PDF]
, 2006 It is known that the global state of a composite quantum system can be completely determined by specifying correlations between measurements performed on subsystems only.

Single Bell inequality to detect genuine nonlocality in three-qubit pure genuinely entangled states
New Journal of PhysicsIt remains an open question whether every pure multipartite state that is genuinely entangled is also genuinely nonlocal. Recently, a new general construction of Bell inequalities allowing the detection of genuine multipartite nonlocality (GMNL) in ...

A quantum loophole to Bell nonlocality
, 2015 We argue that the conclusion of Bell theorem, namely, that there must be spatial non-local correlations in certain experimental situations, does not apply to typical individual measurements performed on entangled EPR pairs. Our claim is based on three points, (i) on the notion of quantum {\it complete measurements}; (ii) on Bell results on local yet ...

Self-testing tilted strategies for maximal loophole-free nonlocality
npj Quantum InformationThe degree of experimentally attainable nonlocality, as gauged by the loophole-free or effective violation of Bell inequalities, remains severely limited due to inefficient detectors.
