Necessary and Sufficient Conditions for Extended Noncontextuality in a Broad Class of Quantum Mechanical Systems
Janne V. Kujala, Ehtibar N. Dzhafarov, Jan-Åke Larsson
The notion of (non)contextuality pertains to sets of properties measured one subset (context) at a time. We extend this notion to include so-called inconsistently connected systems…
Contextuality in Three Types of Quantum-Mechanical Systems
Ehtibar N. Dzhafarov, Janne V. Kujala, Jan-Åke Larsson
We present a formal theory of contextuality for a set of random variables grouped into different subsets (contexts) corresponding to different, mutually incompatible conditions. Wi…
Generalizing Bell-type and Leggett-Garg-type Inequalities to Systems with Signaling
Ehtibar N. Dzhafarov, Janne V. Kujala
Contextuality means non-existence of a joint distribution for random variables recorded under mutually incompatible conditions, subject to certain constraints imposed on how the id…
Measuring Observable Quantum Contextuality
J. Acacio de Barros, Ehtibar N. Dzhafarov, Janne V. Kujala +1
Contextuality is a central property in comparative analysis of classical, quantum, and supercorrelated systems. We examine and compare two well-motivated approaches to contextualit…
Probabilistic Contextuality in EPR/Bohm-type Systems with Signaling Allowed
Janne V. Kujala, Ehtibar N. Dzhafarov
In this chapter, we review a principled way of defining and measuring contextuality in systems with deterministic inputs and random outputs, recently proposed and developed in \cit…
Contextuality is About Identity of Random Variables
Ehtibar N. Dzhafarov, Janne V. Kujala
Contextual situations are those in which seemingly "the same" random variable changes its identity depending on the conditions under which it is recorded. Such a change of identity…
