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…
Contextuality and Informational Redundancy
Ehtibar N. Dzhafarov, Janne V. Kujala
A noncontextual system of random variables may become contextual if one adds to it a set of new variables, even if each of them is obtained by the same context-wise function of the…
