Contextuality or Nonlocality: What Would John Bell Choose Today?

M Kupczynski - Entropy, 2023 - mdpi.com
A violation of Bell-CHSH inequalities does not justify speculations about quantum non-
locality, conspiracy and retro-causation. Such speculations are rooted in a belief that setting …

Causal networks and freedom of choice in bell's theorem

R Chaves, G Moreno, E Polino, D Poderini, I Agresti… - PRX Quantum, 2021 - APS
Bell's theorem is typically understood as the proof that quantum theory is incompatible with
local-hidden-variable models. More generally, we can see the violation of a Bell inequality …

Bell correlations outside physics

C Gallus, EM Pothos, P Blasiak, JM Yearsley… - Scientific Reports, 2023 - nature.com
Correlations are ubiquitous in nature and their principled study is of paramount importance
in scientific development. The seminal contributions from John Bell offer a framework for …

Quantum Nonlocality: how does Nature do it?

M Kupczynski - Entropy, 2024 - mdpi.com
In his article in Science, Nicolas Gisin claimed that quantum correlations emerge from
outside space–time. We explainthat they are due to space-time symmetries. This paper is a …

Contextuality-by-default description of Bell tests: Contextuality as the rule and not as an exception

M Kupczynski - Entropy, 2021 - mdpi.com
Contextuality and entanglement are valuable resources for quantum computing and
quantum information. Bell inequalities are used to certify entanglement; thus, it is important …

[HTML][HTML] Einstein–Podolsky–Rosen–Bohm experiments: A discrete data driven approach

H De Raedt, MI Katsnelson, MS Jattana, V Mehta… - Annals of Physics, 2023 - Elsevier
We take the point of view that building a one-way bridge from experimental data to
mathematical models instead of the other way around avoids running into controversies …

On Applicability of Quantum Formalism to Model Decision Making: Can Cognitive Signaling Be Compatible with Quantum Theory?

A Khrennikov - Entropy, 2022 - mdpi.com
This note is devoted to the problem of signaling (marginal inconsistency) in the Bell-type
experiments with physical and cognitive systems. It seems that in quantum physics, this …

Testing of quantum nonlocal correlations under constrained free will and imperfect detectors

A Sadhu, S Das - Physical Review A, 2023 - APS
In this work, we deal with the relaxation of two central assumptions in standard locally
realistic hidden variable (LRHV) inequalities: free will in choosing measurement settings …

On safe post-selection for Bell tests with ideal detectors: Causal diagram approach

P Blasiak, E Borsuk, M Markiewicz - Quantum, 2021 - quantum-journal.org
Abstract Reasoning about Bell nonlocality from the correlations observed in post-selected
data is always a matter of concern. This is because conditioning on the outcomes is a source …
