Joint Measurability, Einstein-Podolsky-Rosen Steering, and Bell Nonlocality
Physical Review Letters, 2014 We investigate the relation between the incompatibility of quantum measurements and quantum nonlocality. We show that any set of measurements that is not jointly measurable (i.e. incompatible) can be used for demonstrating EPR steering, a form of quantum

Bell nonlocality in networks [PDF]
Reports on Progress in Physics, 2022 Abstract Bell’s theorem proves that quantum theory is inconsistent with local physical models. It has propelled research in the foundations of quantum theory and quantum information science. As a fundamental feature of quantum theory, it impacts predictions far beyond the traditional scenario of the Einstein-Podolsky-Rosen paradox.

Mathematically Proving Bell Nonlocality Motivated by the GHZ Argument
IEEE Access, 2021 Bell nonlocality of quantum states is an important resource in quantum information and then has various applications. It is usually detected by the violation of some Bell’s inequalities and the all-versus-nothing test. In the present paper, we aim

Decoherence-Induced Sudden Death of Entanglement and Bell Nonlocality
Photonics, 2022 Decoherence due to the unwanted interaction between a quantum system and environment leads to the degradation of quantum coherence. In particular, for an entangled state, decoherence makes a loss of entanglement and Bell nonlocality known as entanglement

Bell’s nonlocality and gravity
International Journal of Modern Physics D, 2022 The experimental results that test Bell’s inequality have found strong evidence suggesting that there are nonlocal aspects in nature. Evidently, these nonlocal effects, which concern spacelike separated regions, create an enormous tension between general relativity and quantum mechanics.

Optimal and tight Bell inequalities for state-independent contextuality sets
Physical Review Research, 2023 Two fundamental quantum resources, nonlocality and contextuality, can be connected through Bell inequalities that are violated by state-independent contextuality (SI-C) sets.

Einstein-Podolsky-Rosen Steering for Mixed Entangled Coherent States
Entropy, 2021 By using the Born Markovian master equation, we study the relationship among the Einstein–Podolsky–Rosen (EPR) steering, Bell nonlocality, and quantum entanglement of entangled coherent states (ECSs) under decoherence.

Local hidden variable values without optimization procedures [PDF]
Quantum, 2023 The problem of computing the local hidden variable (LHV) value of a Bell inequality plays a central role in the study of quantum nonlocality. In particular, this problem is the first step towards characterizing the LHV polytope of a given scenario.

Imaging Bell-type nonlocal behavior [PDF]
Science Advances, 2019 We report the violation of a Bell inequality within full-field coincidence images of a phase object probed by entangled photons.

Parameter dependence and Bell nonlocality [PDF]
Physical Review A, 2021 Bell's theorem asserts that no model that satisfies all of the plausible physical assumptions of outcome independence (OI), measurement independence (MI) and Parameter Independence (PI) can reproduce quantum mechanics. Here I find the optimum model that saturates CHSH inequality for the case that outcome independence and measurement independence hold ...
