Quantum correlation games [PDF]
Journal of Physics A: Mathematical and General, 2003 A new approach to play games quantum mechanically is proposed. We consider two players who perform measurements in an EPR-type setting. The payoff relations are defined as functions of correlations, i.e.

Quantum Reactivity: An Indicator of Quantum Correlation. [PDF]
Entropy (Basel), 2019 Geometry is often a valuable guide to complex problems in physics. In this paper, we introduce a novel geometric quantity called quantum reactivity (QR) to probe quantum correlations in higher-dimensional quantum systems. Much like quantum discord, QR is not a measure of quantum entanglement but can be useful in quantum information processes where a ...

Quantum Correlations on Quantum Spaces
International Mathematics Research Notices, 2022 Abstract For given quantum (non-commutative) spaces ${\mathbb {P}}$ and ${\mathbb {O}}$, we study the quantum space of maps ${\mathbb {M}}_{{\mathbb {P}},{\mathbb {O}}}$ from ${\mathbb {P}}$ to ${\mathbb {O}}$. In case of finite quantum spaces, these objects turn out to be behind a large class of maps which generalize the classical ...

CORRELATIONS IN QUANTUM PHYSICS [PDF]
International Journal of Modern Physics B, 2012 We provide a historical perspective of how the notion of correlations has evolved within quantum physics. We begin by reviewing Shannon's information theory and its first application in quantum physics, due to Everett, in explaining the information conveyed during a quantum measurement.

Quantum coherence and correlations in quantum system [PDF]
Scientific Reports, 2015 AbstractCriteria of measure quantifying quantum coherence, a unique property of quantum system, are proposed recently. In this paper, we first give an uncertainty-like expression relating the coherence and the entropy of quantum system. This finding allows us to discuss the relations between the entanglement and the coherence.

QUANTUMNESS OF CORRELATIONS AND ENTANGLEMENT [PDF]
International Journal of Quantum Information, 2011 Generalized measurement schemes on one part of bipartite states, which would leave the set of all separable states insensitive are explored here to understand quantumness of correlations in a more general perspective. This is done by employing linear maps associated with generalized projective measurements.

Journal of the European Optical Society-Rapid Publications, 2023 We investigate the atom-field system in the framework of harmonic oscillators based on deformed Heisenberg algebras. We explore the dynamic characteristics of the considered system under the effect of a nonlinear field.
