Quantum contextuality in the Copenhagen approach
Philosophical Transactions Series A, Mathematical, Physical, and Engineering Sciences, 2019The origin and basis of the notion of quantum contextuality is identified in the Copenhagen approach to quantum mechanics, where context is automatically invoked by its requirement that the experimental arrangement involved in any measurements or set of measurements be taken into account while, in general, the outcome of a measurement may ...

Simultaneous observation of quantum contextuality and quantum nonlocality
Science Bulletin, 2018Quantum nonlocality and quantum contextuality are the most curious properties that change our understanding of nature, and were observed independently in recent decades. One important question is whether both properties can be observed simultaneously. In this paper, we show that in a qutrit-qutrit system we can observe quantum nonlocality and quantum ...

Exploring Quantum Contextuality with Photons
Springer Theses, 2023 Quantum contextuality is one of the most intriguing and peculiar predictions of quantum mechanics. In layman’s terms, it refers to the fact that the result of a single measurement of a physical quantity in quantum mechanics depends on theway the ...

Quantum Contextuality Provides Communication Complexity Advantage
Physical Review Letters, 2023 Despite the conceptual importance of contextuality in quantum mechanics, there is a hitherto limited number of applications requiring contextuality but not entanglement.

Twenty years of quantum contextuality at USTC
JUSTC, 2022 Quantum contextuality is one of the most perplexing and peculiar features of quantum mechanics. Concisely, it refers to the observation that the result of a single measurement in quantum mechanics depends on the set of joint measurements actually ...

Correlations, Contextuality and Quantum Logic
Journal of Philosophical Logic, 2013The authors study states and mixtures of states on simple examples of quantum structures. Particular attention is paid to signaling and deterministic states. Inequalities which distinguish the classical, quantum, and super-quantum approaches are analyzed.

IS QUANTUM MECHANICS CONTEXTUAL?
The Foundations of Quantum Mechanics, 2000The epistemological position underlying the standard interpretation of Quantum Mechanics (QM) can be classified as empirical verificationism (nontestable physical statements have no meaning) . This position can be argued to be responsible for m any puzzling features and "paradoxes" of QM. Nevertheless, it seems soundly based on the Bell-Kochen-Specker (

Stronger Quantum Contextuality
Conference on Lasers and Electro-Optics, 2020We theoretically introduce a family of Hardy-like proofs which lead to stronger noncontextuality inequalities than that of extended KCBS. Meanwhile, we experimentally verify the simplest case of Hardy-like proof based on a fourdimensional photonic system.

Contextuality in quantum systems
American Journal of Physics, 1994The logic of the EPR argument is applied, not to two particles in a line but to one particle in a plane. Contextuality (defined here as a generalization of the notion of nonseparability) among commuting observables is shown to emerge as a result, i.e., although the two orthogonal coordinates characterizing the position of a particle commute ...
