Bell’s theorem for temporal order [PDF]
Nature Communications, 2019 Time has a fundamentally different character in quantum mechanics and in general relativity. Here, the authors consider a thought experiment where a massive body in a spatial superposition leads to entanglement of temporal orders between time-like events,

Simplified quantum optical Stokes observables and Bell’s theorem [PDF]
Scientific Reports, 2022 We discuss a simplified form of Stokes operators for quantum optical fields that involve the known concept of binning. Behind polarization analyzer photon numbers (more generally intensities) are measured.

Nonlocality in Bell’s Theorem, in Bohm’s Theory, and in Many Interacting Worlds Theorising [PDF]
Entropy, 2018 “Locality” is a fraught word, even within the restricted context of Bell’s theorem. As one of us has argued elsewhere, that is partly because Bell himself used the word with different meanings at different stages in his career.

Causal Networks and Freedom of Choice in Bell’s Theorem [PDF]
PRX Quantum, 2021 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 as witnessing the impossibility of explaining quantum correlations ...

Discretization of the Bloch sphere, fractal invariant sets and Bell's theorem. [PDF]
Proc Math Phys Eng Sci, 2020 An arbitrarily dense discretization of the Bloch sphere of complex Hilbert states is constructed, where points correspond to bit strings of fixed finite length.

Kupczynski’s Contextual Locally Causal Probabilistic Models Are Constrained by Bell’s Theorem [PDF]
Quantum Reports, 2023 In a sequence of papers, Marian Kupczynski has argued that Bell’s theorem can be circumvented if one takes correct account of contextual setting-dependent parameters describing measuring instruments. We show that this is not true.

Counterfactual restrictions and Bell’s theorem [PDF]
Journal of Physics Communications, 2019 We show that the ability to consider counterfactual situations is a necessary assumption of Bell’s theorem, and that, to allow Bell inequality violations while maintaining all other assumptions, we just require certain measurement choices be ...

Does Geometric Algebra Provide a Loophole to Bell’s Theorem? [PDF]
Entropy, 2019 In 2007, and in a series of later papers, Joy Christian claimed to refute Bell’s theorem, presenting an alleged local realistic model of the singlet correlations using techniques from geometric algebra (GA).

Gull’s Theorem Revisited [PDF]
Entropy, 2022 In 2016, Steve Gull has outlined has outlined a proof of Bell’s theorem using Fourier theory. Gull’s philosophy is that Bell’s theorem (or perhaps a key lemma in its proof) can be seen as a no-go theorem for a project in distributed computing with ...
