Causal Networks and Freedom of Choice in Bell’s Theorem
PRX Quantum, 2021 Bell’s theorem is typically understood as the proof that quantum theory is incompatible with local-hidden-variable models. More generally, we can see the violation of a Bell inequality as witnessing the impossibility of explaining quantum correlations ...

Spin Bath Decoherence of Quantum Entanglement [PDF]
, 2005 We study an analytically solvable model for decoherence of a two spin system embedded in a large spin environment. As a measure of entanglement, we evaluate the concurrence for the Bell states (Einstein-Podolsky-Rosen pairs).

European Physical Journal C: Particles and Fields, 2023 Quantum entanglement of weak interaction gauge bosons produced at colliders can be explored by computing the corresponding polarization density matrix. To this end, we consider the Higgs boson decays $$H\rightarrow W W^*$$ H → W W ∗ and $$H\rightarrow Z ...

Violation of Bells inequality using continuous variable measurements [PDF]
, 2018 A Bell inequality is a fundamental test to rule out local hidden variable model descriptions of correlations between two physically separated systems.

A Probability Model for the Bell Experiment
Quantum ReportsThe Bell inequality constrains the outcomes of measurements on pairs of distant entangled particles. The Bell contradiction states that the Bell inequality is inconsistent with the calculated outcomes of these quantum experiments.

Correlations in star networks: from Bell inequalities to network inequalities
New Journal of Physics, 2017 The problem of characterizing classical and quantum correlations in networks is considered. Contrary to the usual Bell scenario, where distant observers share a physical system emitted by one common source, a network features several independent sources,

Genuine multipartite Bell inequality for device-independent conference key agreement
Physical Review Research, 2020 A class of genuine multipartite Bell inequalities is presented, which is designed for multipartite device-independent (DI) quantum key distribution (QKD).

Cryptography, 2020 Loophole-free violations of Bell inequalities are crucial for fundamental tests of quantum nonlocality. They are also important for future applications in quantum information processing, such as device-independent quantum key distribution.

Bell Inequality from Holographic Gravity
EPJ Web of Conferences, 2018 We study a holographic model of an EPR pair at the boundary of bulk gravity, and use Bell inequality as a sharp test of entanglement. By revealing how Bell inequality is violated by gravity in the bulk, our study sheds light on the entanglement of the ...
