The Degree of Quantum Contextuality in Terms of Concurrence for the KCBS Scenario [PDF]
International Journal of Theoretical Physics, 2022 Quantum contextuality is the key concept which explains the fact that the result of a measurement is not independent of the context in which it is found.

Experimental Test of High-Dimensional Quantum Contextuality Based on Contextuality Concentration. [PDF]
Physical Review Letters, 2022 Contextuality is a distinctive feature of quantum theory and a fundamental resource for quantum computation. However, existing examples of contextuality in high-dimensional systems lack the necessary robustness required in experiments.

Hypergraph framework for irreducible noncontextuality inequalities from logical proofs of the Kochen-Specker theorem [PDF]
Quantum, 2020 Kochen-Specker (KS) theorem reveals the inconsistency between quantum theory and any putative underlying model of it satisfying the constraint of KS-noncontextuality.

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.

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 ...

Revealing quantum contextuality using a single measurement device [PDF]
Physical Review A, 2021 In this work we analyse the notion of measurement non-contextuality (MNC) and identify contextual scenarios which involve sequential measurements of only a single measurement device.

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.

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.
