Kochen-Specker Contextuality

, 2022
A central result in the foundations of quantum mechanics is the Kochen-Specker theorem. In short, it states that quantum mechanics is in conflict with classical models in which the result of a measurement does not depend on which other compatible ...

Optimal and tight Bell inequalities for state-independent contextuality sets

Physical Review Research, 2023
Two fundamental quantum resources, nonlocality and contextuality, can be connected through Bell inequalities that are violated by state-independent contextuality (SI-C) sets.

Contextuality in Neurobehavioural and Collective Intelligence Systems

Quantum Reports, 2021
Contextuality is often described as a unique feature of the quantum realm, which distinguishes it fundamentally from the classical realm. This is not strictly true, and stems from decades of the misapplication of Kolmogorov probability.

Contextuality as a resource for measurement-based quantum computation beyond qubits

New Journal of Physics, 2018
Contextuality—the obstruction to describing quantum mechanics in a classical statistical way—has been proposed as a resource that powers quantum computing.

Contextuality in Classical Physics and Its Impact on the Foundations of Quantum Mechanics

Entropy, 2021
It is shown that the hallmark quantum phenomenon of contextuality is present in classical statistical mechanics (CSM). It is first shown that the occurrence of contextuality is equivalent to there being observables that can differentiate between pure and

A mathematical framework for operational fine tunings [PDF]

Quantum, 2023
In the framework of ontological models, the inherently nonclassical features of quantum theory always seem to involve properties that are fine tuned, i.e. properties that hold at the operational level but break at the ontological level.

Constraining meanings with contextuality

, 2022
In this paper, we defend two claims. First, we argue that a notion of contextuality that has been formalized in physics and psychology is applicable to linguistic contexts.

An Order-Theoretic Quantification of Contextuality

Information, 2014
In this essay, I develop order-theoretic notions of determinism and contextuality on domains and topoi. In the process, I develop a method for quantifying contextuality and show that the order-theoretic sense of contextuality is analogous to the sense ...

Bosonic Indistinguishability-Dependent Contextuality

, 2021
We uncover a form of quantum contextuality that connects maximal contextuality to boson indistinguihability in a similar way maximal nonlocality with respect to the Clauser-Horne-Shimony-Holt Bell inequality is connected to maximal entanglement.
