A versatile construction of Bell inequalities for the multipartite scenario

New Journal of Physics, 2019
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 ...

Maximal Violation of Bell's Inequalities for Continuous Variable Systems

, 2002
We generalize Bell's inequalities to biparty systems with continuous quantum variables. This is achieved by introducing the Bell operator in perfect analogy to the usual spin-1/2 systems.

Einstein-Podolsky-Rosen correlations and Bell correlations in the simplest scenario

, 2017
Einstein-Podolsky-Rosen (EPR) steering is an intermediate type of quantum nonlocality which sits between entanglement and Bell nonlocality. A set of correlations is Bell nonlocal if it does not admit a local hidden variable (LHV) model, while it is EPR ...

Bell nonlocality in the turbulent atmosphere [PDF]

Physical Review A, 2016
Violations of Bell inequalities are better preserved by turbulent atmospheric channels than by comparable optical fibers in the scenario of copropagating entangled photons [A.A. Semenov and W. Vogel, Phys. Rev. A 81, 023835 (2010); arXiv:0909.2492]. Here we reexamine this result for the case of counterpropagation also considering the fact that each ...

Discriminating quantum correlations with networking quantum teleportation

Physical Review Research, 2020
The Bell inequality, and its substantial experimental violation, offers a seminal paradigm for showing that the world is not in fact locally realistic.

Genuine multipartite nonlocality in the one-dimensional ferromagnetic spin-1/2 chain

, 2017
Genuine multipartite entanglement has been found in some spin chain systems. However, genuine multipartite nonlocality, which is much rarer than genuine multipartite entanglement, has never been found in any spin chain system.

Measurement incompatibility does not give rise to Bell violation in general

New Journal of Physics, 2018
In the case of a pair of two-outcome measurements, incompatibility is equivalent to Bell nonlocality. Indeed, any pair of incompatible two-outcome measurements can violate the Clauser–Horne–Shimony–Holt Bell inequality, which has been proven by Wolf et ...

Get Rid of Nonlocality from Quantum Physics

Entropy, 2019
This paper is aimed to dissociate nonlocality from quantum theory. We demonstrate that the tests on violation of the Bell type inequalities are simply statistical tests of local incompatibility of observables. In fact, these are tests on violation of the

Quantum Correlations in non-Markovian Environments

, 2010
We have studied the analytical Markovian and non-Markovian dynamics of quantum correlations, such as entanglement, quantum discord and Bell nonlocalities for three noisy qubits.
