Simplicial quantum contextuality [PDF]
Quantum, 2023 We introduce a new framework for contextuality based on simplicial sets, combinatorial models of topological spaces that play a prominent role in modern homotopy theory.

npj Quantum InformationWe demonstrate that the contextuality of measurement selection can enhance the precision of quantum metrology with a simple linear optical experiment. Contextuality is a nonclassical property known as a resource for various quantum information processing

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.

Experimental observation of Hardy-like quantum contextuality [PDF]
Physical Review Letters, 2014 Contextuality is a fundamental property of quantum theory and a critical resource for quantum computation. Here, we experimentally observe the arguably cleanest form of contextuality in quantum theory [A. Cabello \emph{et al.}, Phys. Rev. Lett.

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.

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.

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 ...

Classifying Space for Quantum Contextuality [PDF]
Annales Henri Poincaré, 2021 We construct a topological space to study contextuality in quantum mechanics. The resulting space is a classifying space in the sense of algebraic topology. Cohomological invariants of our space correspond to physical quantities relevant to the study of contextuality.
