Contextuality and Indistinguishability [PDF]
Entropy, 2017 It is well known that in quantum mechanics we cannot always define consistently properties that are context independent. Many approaches exist to describe contextual properties, such as Contextuality by Default (CbD), sheaf theory, topos theory, and non ...

On the Cohomology of Contextuality [PDF]
Electronic Proceedings in Theoretical Computer Science, 2017 Recent work by Abramsky and Brandenburger used sheaf theory to give a mathematical formulation of non-locality and contextuality. By adopting this viewpoint, it has been possible to define cohomological obstructions to the existence of global sections ...

New Journal of Physics, 2023 Quantum contextuality is one of the most recognized resources in quantum communication and computing scenarios. We provide a new quantifier of this resource, the rank of contextuality (RC).

Quantum Contextuality with Stabilizer States [PDF]
Entropy, 2013 The Pauli groups are ubiquitous in quantum information theory because of their usefulness in describing quantum states and operations and their readily understood symmetry properties.

Contextual Fraction as a Measure of Contextuality [PDF]
Physical Review Letters, 2017 We consider the contextual fraction as a quantitative measure of contextuality of empirical models, i.e. tables of probabilities of measurement outcomes in an experimental scenario. It provides a general way to compare the degree of contextuality across measurement scenarios; it bears a precise relationship to violations of Bell inequalities; its value,

The Logic of Contextuality [PDF]
, 2021 Contextuality is a key signature of quantum non-classicality, which has been shown to play a central role in enabling quantum advantage for a wide range of information-processing and computational tasks.

Quantifying Contextuality [PDF]
Physical Review Letters, 2014 Contextuality is central to both the foundations of quantum theory and to the novel information processing tasks. Although it was recognized before Bell's nonlocality, despite some recent proposals, it still faces a fundamental problem: how to quantify its presence? In this work, we provide a framework for quantifying contextuality.

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.

Translation, meaning and the duo colloqium : contextuality in translation and interpreting
, 2022 This chapter summarises the past and present of the Lodz-Maastricht and Lodz-ZHAW Duo Colloquia on Translation and Meaning through the lens of its latest iteration on context, contexts and contextuality in translation and interpreting.
