Causal hierarchy of multipartite Bell nonlocality [PDF]
Quantum, 2017 As with entanglement, different forms of Bell nonlocality arise in the multipartite scenario. These can be defined in terms of relaxations of the causal assumptions in local hidden-variable theories.

Entanglement without hidden nonlocality
New Journal of Physics, 2016 We consider Bell tests in which the distant observers can perform local filtering before testing a Bell inequality. Notably, in this setup, certain entangled states admitting a local hidden variable model in the standard Bell scenario can nevertheless ...

Nonlocality activation in a photonic quantum network [PDF]
Nature CommunicationsBell nonlocality refers to correlations between two distant, entangled particles that challenge classical notions of local causality. Beyond its foundational significance, nonlocality is crucial for device-independent technologies like quantum key ...

Reviews of Modern Physics, 2014 Bell's 1964 theorem, which states that the predictions of quantum theory cannot be accounted for by any local theory, represents one of the most profound developments in the foundations of physics.

Nonlocality in quantum cloning states [PDF]
Scientific ReportsThis study investigates the nonlocality characteristics of output states produced by a universal quantum cloning machine, with particular emphasis on the Bell-CHSH inequality violations exhibited by the two-qubit reduced states of cloned outputs. Through

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

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.
