Classicality and Bell’s theorem [PDF]
European Journal for Philosophy of Science, 2023 A widespread view among physicists is that Bell’s theorem rests on an implicit assumption of “classicality,” in addition to locality. According to this understanding, the violation of Bell’s inequalities poses no challenge to locality, but simply ...

Implications of Local Friendliness Violation for Quantum Causality [PDF]
Entropy, 2021 We provide a new formulation of the Local Friendliness no-go theorem of Bong et al. [Nat. Phys. 16, 1199 (2020)] from fundamental causal principles, providing another perspective on how it puts strictly stronger bounds on quantum reality than Bell’s ...

Beyond Bell's theorem: correlation scenarios [PDF]
New Journal of Physics, 2012 Bell's theorem witnesses that the predictions of quantum theory cannot be reproduced by theories of local hidden variables in which observers can choose their measurements independently of the source.

Beyond Bell's theorem: realism and locality without Bell-type correlations. [PDF]
Sci Rep, 2017 The long-lasting view of entanglement as the characteristic trait of quantum mechanics has been recently challenged by experimental demonstrations of non-quantum entanglement.

Bell’s “Theorem”: loopholes vs. conceptual flaws [PDF]
Open Physics, 2017 An historical overview and detailed explication of a critical analysis of what has become known as Bell’s Theorem to the effect that, it should be impossible to extend Quantum Theory with the addition of local, real variables so as to obtain a version ...

Experimental Counterexample to Bell’s Locality Criterion [PDF]
Entropy, 2022 The EPR paradox was caused by the provision that quantum variables must have pre-existing values. This type of “hidden property realism” was later falsified by Bell’s Theorem.

Ontic and Epistemic States in the Theory of Spacetime-Local Beables [PDF]
EntropyBell’s theorem rules out developing a locally causal theory to describe quantum phenomena. Many take this to imply that any model of quantum entanglement must employ variables (called beables by Bell) which follow nonlocal rules, even though signaling is

Hidden variables and Bell’s theorem: Local or not? [PDF]
THEORIA. An International Journal for Theory, History and Foundations of ScienceBell’s inequality is an empirical constraint on theories with hidden variables, which Einstein, Podolsky and Rosen argued are needed to explain observed perfect correlations if keeping locality.

Experimental quantum key distribution certified by Bell's theorem [PDF]
Nature, 2021 Cryptographic key exchange protocols traditionally rely on computational conjectures such as the hardness of prime factorization1 to provide security against eavesdropping attacks.

Bell’s theorem allows local theories of quantum mechanics [PDF]
Nature Physics, 2022 A recent Nature Physics editorial (Nat. Phys. (2022) 18, 961) falsely claims ``any theory that uses hidden variables still requires non-local physics.'' We correct this claim and explain why it is important to get this right.
