Analytic Philosophy, 2021 AbstractMy double aim in this paper is to argue for the claims that, when they are formed in certain ways, some judgements expressed by “I am here now” are both (a) apriori (although not solely in virtue of their meaning), and (b) necessary (albeit trivially so).

Assumption-Free Derivation of the Bell-Type Criteria of Contextuality/Nonlocality
Entropy, 2021 Bell-type criteria of contextuality/nonlocality can be derived without any falsifiable assumptions, such as context-independent mapping (or local causality), free choice, or no-fine-tuning.

State-independent test of quantum contextuality with either single photons or coherent light
npj Quantum Information, 2021 Contextuality is a phenomenon at the heart of quantum mechanics different from classical behavior and has been recently identified as a resource in quantum information processing. Experimental demonstration of contextuality is thus an important goal.

Bell non-locality and Kochen-Specker contextuality: How are they connected? [PDF]
, 2021 Bell non-locality and Kochen-Specker (KS) contextuality are logically independent concepts, fuel different protocols with quantum vs classical advantage, and have distinct classical simulation costs.

Topological Contextuality and Anyonic Statistics of Photonic-Encoded Parafermions
PRX Quantum, 2021 Quasiparticle poisoning, expected to arise during the measurement of the Majorana zero-mode state, poses a fundamental problem for the realization of Majorana-based quantum computation.

Bounding and Simulating Contextual Correlations in Quantum Theory
PRX Quantum, 2021 We introduce a hierarchy of semidefinite relaxations of the set of quantum correlations in generalized contextuality scenarios. This constitutes a simple and versatile tool for bounding the magnitude of quantum contextuality.

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 ...

IEEE Transactions on Image Processing, 2012 Histograms have been widely used for feature representation in image and video content analysis. However, due to the orderless nature of the summarization process, histograms generally lack spatial information. This may degrade their discrimination capability in visual classification tasks.

Measurement incompatibility and steering are necessary and sufficient for operational contextuality
Physical Review Research, 2020 Contextuality is a signature of operational nonclassicality in the outcome statistics of an experiment. This notion of nonclassicality applies to a breadth of physical phenomena. Here, we establish its relation to two fundamental nonclassical entities in

Sum-of-squares decompositions for a family of noncontextuality inequalities and self-testing of quantum devices [PDF]
Quantum, 2020 Violation of a noncontextuality inequality or the phenomenon referred to `quantum contextuality' is a fundamental feature of quantum theory. In this article, we derive a novel family of noncontextuality inequalities along with their sum-of-squares ...
