Degrees, Levels, and Profiles of Contextuality

Ehtibar N. Dzhafarov, Victor H. Cervantes

We introduce a new notion, that of a contextuality profile of a system of random variables. Rather than characterizing a system's contextuality by a single number, its overall degr…

Quantum mechanics is compatible with counterfactual definiteness

Janne V. Kujala, Ehtibar N. Dzhafarov

Counterfactual definiteness (CFD) means that if some property is measured in some context, then the outcome of the measurement would have been the same had this property been measu…

Hidden variables, free choice, context-independence, and all that

Ehtibar N. Dzhafarov

This paper provides a systematic account of the hidden variable models (HVMs) formulated to describe systems of random variables with mutually exclusive contexts. Any such system c…

Hypercyclic systems of measurements and patterns of contextuality

Victor H. Cervantes, Ehtibar N. Dzhafarov

We consider four measures of contextuality, chosen for being based on the fundamental properties of the notion of contextuality, and for being applicable to arbitrary systems of me…

Contextuality with disturbance and without: Neither can violate substantive requirements the other satisfies

Ehtibar Dzhafarov, Janne V. Kujala

Contextuality was originally defined only for consistently connected systems of random variables (those without disturbance/signaling). Contextuality-by-Default theory (CbD) offers…
