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.

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

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 ...

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.

Power spectral density and the brain
Canadian Journal of Statistics, EarlyView.Abstract Time series from M/EEG (magneto/electroencephalography) and ECoG (electrocorticography) recordings are common sources of information about brain function. The power spectral density (PSD) preserves much of this information, up to second order. In the current decade, a burst of brain diagnostics using the slope of log(PSD) has appeared.

Deterministic all-versus-nothing proofs of Bell nonlocality based on non-stabilizer states
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 ...
