Quantum Contextuality and Indeterminacy [PDF]

Entropy, 2020
The circumstances of measurement have more direct significance in quantum than in classical physics, where they can be neglected for well-performed measurements.

Chromatic Quantum Contextuality [PDF]

Entropy
Chromatic quantum contextuality is a criterion of quantum nonclassicality based on (hyper)graph coloring constraints. If a quantum hypergraph requires more colors than the number of outcomes per maximal observable (context), it lacks a classical ...

Statistical Signatures of Quantum Contextuality [PDF]

Entropy
Quantum contextuality describes situations where the statistics observed in different measurement contexts cannot be explained by a measurement of the independent reality of the system.

Quantum Contextuality [PDF]

Quantum, 2023
Quantum contextual sets have been recognized as resources for universal quantum computation, quantum steering and quantum communication. Therefore, we focus on engineering the sets that support those resources and on determining their structures and ...

Contextuality in Collective Intelligence: Not There Yet [PDF]

Entropy, 2023
Type I contextuality or inconsistent connectedness is a fundamental feature of both the classical as well as the quantum realms. Type II contextuality (true contextuality or CHSH-type contextuality) is frequently asserted to be specific to the quantum ...

Demonstrating quantum contextuality of indistinguishable particles by a single family of noncontextuality inequalities. [PDF]

Sci Rep, 2015
Quantum theory has the intriguing feature that is inconsistent with noncontextual hidden variable models, for which the outcome of a measurement does not depend on which other compatible measurements are being performed concurrently. While various proofs

Violation of Leggett–Garg Inequality in Perceiving Cup-like Objects and Cognitive Contextuality [PDF]

Entropy
This paper is devoted to an experimental investigation of cognitive contextuality inspired by quantum contextuality research. This contextuality is related to, but not identical to context-sensitivity which is well-studied in cognitive psychology and ...

Are Human Judgments of Real and Fake Faces Quantum-like Contextual? [PDF]

Entropy
This paper describes a crowdsourced experiment in which participants were asked to judge which of two simultaneously presented facial images (one real, one AI-generated) was fake.

Quantum Contextual Hypergraphs, Operators, Inequalities, and Applications in Higher Dimensions [PDF]

Entropy
Quantum contextuality plays a significant role in supporting quantum computation and quantum information theory. The key tools for this are the Kochen–Specker and non-Kochen–Specker contextual sets.

Characterising and bounding the set of quantum behaviours in contextuality scenarios [PDF]

Quantum, 2021
The predictions of quantum theory resist generalised noncontextual explanations. In addition to the foundational relevance of this fact, the particular extent to which quantum theory violates noncontextuality limits available quantum advantage in ...
