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 ...

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.

Loophole-free Bell inequality violation experiments verifying the realism and locality principles
Frontiers in PhysicsThe aim of this study is to produce a simulation of EPR experiments violating the CHSH-Bell inequalities using physically interpretable objects (properties defined before measurement) and interactions (no supraliminal communication), without influence ...

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

Experimental violation of local causality in a quantum network
Nature Communications, 2017 Bell’s theorem has important implications for quantum information processing. Here the authors experimentally investigate the violation of a Bell-like inequality in the case of distant parties whose correlations are mediated by independent sources, a ...

Dr. Bertlmann’s Socks in a Quaternionic World of Ambidextral Reality
IEEE Access, 2020 Unlike our basic theories of space and time, quantum mechanics is not a locally causal theory. Moreover, it is widely believed that any hopes of restoring local causality within any realistic theory have been undermined by Bell's theorem and the ...

Measurement problem and local hidden variables with entangled photons
Open Physics, 2017 It is shown that there is no remote action with polarization measurements of photons in singlet state. A model is presented introducing a hidden parameter which determines the polarizer output.

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.

The photon identification loophole in EPRB experiments: computer models with single-wing selection
Open Physics, 2017 Recent Einstein-Podolsky-Rosen-Bohm experiments [M. Giustina et al. Phys. Rev. Lett. 115, 250401 (2015); L. K. Shalm et al. Phys. Rev. Lett. 115, 250402 (2015)] that claim to be loophole free are scrutinized.

Motive and Opportunity: Order Choice in a Limit Order Book With Dispersed Information
International Journal of Finance &Economics, EarlyView.ABSTRACT We test predictions of market microstructure theory relating to the determinants of order choice in a limit order book where information is dispersed among traders. Using an experimental limit order book, with a large state space, we find that informed traders exhibit patience, compatible with the ‘waiting game’ behaviour described in Foster ...
