This is a review devoted to the complementarity–contextuality interplay with connection to
the Bell inequalities. Starting the discussion with complementarity, I point to contextuality as …

Bell-CHSH inequalities are trivial algebraic properties satisfied by each line of an Nx4
spreadsheet containing±1 entries, thus it is surprising that their violation in some …

John Bell, FRS was one of the leading expositors and interpreters of modern quantum
theory. He is particularly famous for his discovery of the crucial difference between the …

Fifty years ago—in 1963, to be precise—the British physicist Trevor Marshall published a
paper in the Proceedings of the Royal Society under the short title Random Electrodynamics …

This paper is a new step towards understanding why “quantum nonlocality” is a misleading
concept. Metaphorically speaking,“quantum nonlocality” is Janus faced. One face is an …

This note is a part of my effort to rid quantum mechanics (QM) nonlocality. Quantum
nonlocality is a two faced Janus: one face is a genuine quantum mechanical nonlocality …

Spin is a fundamental and distinctive property of the electron, having far-reaching
implications. Yet its purely formal treatment often blurs the physical content and meaning of …

Our aim is to make a step toward clarification of foundations for the notion of entanglement
(both physical and mathematical) by representing it in the conditional probability framework …

Bell-type inequalities are proven using oversimplified probabilistic models and/or
counterfactual definiteness (CFD). If setting-dependent variables describing measuring …

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 …
