The Bell Theorem Revisited: Geometric Phases in Gauge Theories

Frontiers in Physics, 2020
The Bell theorem stands as an insuperable roadblock in the path to a very desired intuitive solution of the EPR paradox and, hence, it lies at the core of the current lack of a clear interpretation of the quantum formalism.

No-Signalling Is Equivalent To Free Choice of Measurements [PDF]

Electronic Proceedings in Theoretical Computer Science, 2014
No-Signalling is a fundamental constraint on the probabilistic predictions made by physical theories. It is usually justified in terms of the constraints imposed by special relativity.

Quantum Team Logic and Bell's Inequalities [PDF]

, 2015
A logical approach to Bell's Inequalities of quantum mechanics has been introduced by Abramsky and Hardy [2]. We point out that the logical Bell's Inequalities of [2] are provable in the probability logic of Fagin, Halpern and Megiddo [4].

Beyond Bell's theorem: correlation scenarios

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.

Cohomology of Effect Algebras [PDF]

Electronic Proceedings in Theoretical Computer Science, 2017
We will define two ways to assign cohomology groups to effect algebras, which occur in the algebraic study of quantum logic. The first way is based on Connes' cyclic cohomology. The resulting cohomology groups are related to the state space of the effect

Disentangling the Quantum World

Entropy, 2015
Correlations related to quantum entanglement have convinced many physicists that there must be some at-a-distance connection between separated events, at the quantum level. In the late 1940s, however, O.

Causarum Investigatio and the Two Bell's Theorems of John Bell [PDF]

, 2015
"Bell's theorem" can refer to two different theorems that John Bell proved, the first in 1964 and the second in 1976. His 1964 theorem is the incompatibility of quantum phenomena with the joint assumptions of Locality and Predetermination.

Witnessing Nonclassicality in a Causal Structure with Three Observable Variables

PRX Quantum, 2023
Seen from the modern lens of causal inference, Bell’s theorem is nothing other than the proof that a specific classical causal model cannot explain quantum correlations.

Bell’s “Theorem”: loopholes vs. conceptual flaws

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 ...
