Bell on Bell's theorem: The changing face of nonlocality [PDF]
, 2014 Between 1964 and 1990, the notion of nonlocality in Bell's papers underwent a profound change as his nonlocality theorem gradually became detached from quantum mechanics, and referred to wider probabilistic theories involving correlations between ...

, 2019 Nonlocality was discovered by John Bell in 1964, in the context of the debates about quantum theory, but is a phenomenon that can be studied in its own right.

Dynamical Bell Nonlocality [PDF]
, 2020 Quantum mechanics is a highly nonlocal theory of nature. Quantum systems exhibit correlations which cannot be described by any classical theory of locality.

Catalytic Activation of Bell Nonlocality [PDF]
Physical Review LettersInternational audienceThe correlations of certain entangled states can be perfectly simulated classically via a local model. Hence such states are termed Bell local, as they cannot lead to Bell inequality violation.

Classical causal models cannot faithfully explain Bell nonlocality or Kochen-Specker contextuality in arbitrary scenarios [PDF]
Quantum, 2021 In a recent work, it was shown by one of us (EGC) that Bell-Kochen-Specker inequality violations in phenomena satisfying the no-disturbance condition (a generalisation of the no-signalling condition) cannot in general be explained with a faithful ...

Trade-off relations between Bell nonlocality and local Kochen–Specker contextuality in generalized Bell scenarios [PDF]
New Journal of PhysicsThe relations between Bell nonlocality and Kochen–Specker contextuality have been subject of research from many different perspectives in the last decades.

Genuine four-partite Bell nonlocality in the curved spacetime [PDF]
European Physical Journal C: Particles and FieldsThe quantum Bell nonlocality plays a crucial role in quantum information processing. In this paper, we first obtain the quantitative analytical expression of the genuine four-partite Bell nonlocality of any 4-qubit quantum state. Then, we investigate and

Bell Nonlocality in Hybrid Networks
Advanced Physics Research, Volume 5, Issue 1, January 2026.This study explores nonlocal correlations in the hybrid networks, including classical, quantum and no‐signaling resource emitting local hidden variables, quantum stabilizer states and no‐signaling systems to variant observers. We construct the Bell operators using stabilizing operators and then find the upper bounds in hybrid networks.

Entanglement without hidden nonlocality [PDF]
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 ...

Deterministic all-versus-nothing proofs of Bell nonlocality based on non-stabilizer states [PDF]
New Journal of Physics, 2023 The all-versus-nothing proof of Bell nonlocality is a prominent demonstration of Bell’s theorem without inequalities. There are two kinds of such proofs: the deterministic all-versus-nothing proof and the probabilistic all-versus-nothing proof, which ...
