Entanglement and quantum correlation measures for quantum multipartite mixed states [PDF]
Scientific Reports, 2023 Entanglement, and quantum correlation, are precious resources for quantum technologies implementation based on quantum information science, such as quantum communication, quantum computing, and quantum interferometry. Nevertheless, to our best knowledge,

Quantum correlation in a nano-electro-optomechanical system enhanced by an optical parametric amplifier and Coulomb-type interaction [PDF]
Scientific Reports, 2023 In this paper, we investigated the quantum correlation of nano-electro-optomechanical system enhanced by an optical parametric amplifier (OPA) and Coulomb-type interaction. In particular, we consider a hybrid system consisting of a cavity and two charged

An inherently infinite-dimensional quantum correlation [PDF]
Nature Communications, 2020 The existence of nonlocal correlations which cannot be attained exactly by finite-dimensional systems, but can be attained by infinite-dimensional ones, has been the subject of several theoretical efforts.

Unveiling Sudden Transitions Between Classical and Quantum Decoherence in the Hyperfine Structure of Hydrogen Atoms [PDF]
EntropyThis paper investigates the dynamics of quantum and classical geometric correlations in the hyperfine structure of the hydrogen atom under pure dephasing noise, focusing on the interplay between entangled initial states and environmental effects.

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 ...

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.

Quantum correlation in superconducting Two-Qubit systems [PDF]
Mathematics and Computational Sciences, 2021 We consider a two-qubit superconducting system. By introducing the two measures of Concurrence and discord, we calculate the value of the correlations of this system and also determine the changes of the correlations of this system with respect to the ...

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 ...
