Discriminating quantum correlations with networking quantum teleportation [PDF]
Physical Review Research, 2020 The Bell inequality, and its substantial experimental violation, offers a seminal paradigm for showing that the world is not in fact locally realistic.

Quantum Correlations on Quantum Spaces [PDF]
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 Discord: A Measure of the Quantumness of Correlations [PDF]
Physical Review Letters, 2001 Two classically identical expressions for the mutual information generally differ when the systems involved are quantum. This difference defines the quantum discord. It can be used as a measure of the quantumness of correlations. Separability of the density matrix describing a pair of systems does not guarantee vanishing of the discord, thus showing ...

Macroscopically Nonlocal Quantum Correlations [PDF]
Physical Review Letters, 2021 It is usually believed that coarse-graining of quantum correlations leads to classical correlations in the macroscopic limit. Such a principle, known as macroscopic locality, has been proved for correlations arising from independent and identically distributed (IID) entangled pairs. In this letter we consider the generic (non-IID) scenario.

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.

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.
