Uniqueness of all fundamental noncontextuality inequalities
Physical Review Research, 2020 Contextuality is one way of capturing the nonclassicality of quantum theory. The contextual nature of a theory is often witnessed via the violation of noncontextuality inequalities—certain linear inequalities involving probabilities of measurement events.

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.

New Journal of Physics, 2023 Contextuality is a striking feature of our nature predicted by quantum theory and tested by various experiments. In a qubit system, testing contextuality requires scenarios distinct from traditional ones for systems with dimension of three or greater. In

Optimal allocation of quantum resources [PDF]
Quantum, 2021 The optimal allocation of resources is a crucial task for their efficient use in a wide range of practical applications in science and engineering. This paper investigates the optimal allocation of resources in multipartite quantum systems. In particular,

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

Optimal measurement structures for contextuality applications
npj Quantum Information, 2023 The Kochen-Specker (KS) theorem is a cornerstone result in the foundations of quantum mechanics describing the fundamental difference between quantum theory and classical non-contextual theories.

Contextuality and Indistinguishability
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 ...
