Contextuality and Wigner function negativity in qubit quantum computation [PDF]
, 2017 We describe a scheme of quantum computation with magic states on qubits for which contextuality is a necessary resource possessed by the magic states.

Contextualizing ontologies [PDF]
Journal of Web Semantics, 2004 Ontologies are shared models of a domain that encode a view which is common to a set of different parties. Contexts are local models that encode a party's subjective view of a domain. In this paper, we show how ontologies can be contextualized, thus acquiring certain useful properties that a pure shared approach cannot provide.

Kantian Review, 2018 AbstractThis article builds on David Velleman’s recent work on moral relativism to argue that Kant’s account of moral judgement is best read in a contextualist manner. More specifically, I argue that while for Kant the form of moral judgement is invariant, substantive moral judgements are nonetheless context-dependent.

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.

Measurement contextuality and Planck’s constant
New Journal of Physics, 2018 Contextuality is a necessary resource for universal quantum computation and non-contextual quantum mechanics can be simulated efficiently by classical computers in many cases. Orders of Planck’s constant, ℏ, can also be used to characterize the classical-

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.

, 2017 Contextuality is a fundamental feature of quantum theory and is necessary for quantum computation and communication. Serious steps have therefore been taken towards a formal framework for contextuality as an operational resource.

Contextuality without Incompatibility
Physical Review Letters, 2023 The existence of incompatible measurements is often believed to be a feature of quantum theory which signals its inconsistency with any classical worldview. To prove the failure of classicality in the sense of Kochen-Specker noncontextuality, one does indeed require sets of incompatible measurements.

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 ...
