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 ...

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 ...

Quantum Contextuality and Locality
2020Στην παρούσα διπλωματική εργασία μελετήσαμε τις έννοιες του κβαντικού πλαισίου και της τοπικότητας. Αρχικά παραθέτουμε μία παρουσίαση των εννοιών και ακολουθεί μια παρουσίαση των σημαντικότερων θεωρημάτων σχετικών με το θέμα, δηλαδή του θεωρήματος του Bell και του θεωρήματος των Kochen και Specker. Κατόπιν, προσεγγίζουμε τις προαναφερθείσες έννοιες από

Quantum contextuality, finite geometry & quantum computation
Contextualité quantique, géométries finies & informatique quantique Le développement de machines quantiques de tailles modestes accessibles en ligne permet aujourd'hui de réaliser des expériences sur des calculateurs à distance. L'avantage de l'informatique quantique repose sur des phénomènes strictement non classiques, tels que la ...openaire +1 more source
