The tripartite quantum-memory-assisted entropic uncertainty relation and upper bound on shareability of quantum discord [PDF]
Quantum discord and quantum uncertainty are two important features of the quantum world. In this work, the relation between entropic uncertainty relation and the shareability of quantum discord is studied.

Quantum Discord, Thermal Discord, and Entropy Generation in the Minimum Error Discrimination Strategy [PDF]
We study the classical and quantum correlations in the minimum error discrimination (ME) of two non-orthogonal pure quantum states. In particular, we consider quantum discord, thermal discord and entropy generation.

Entanglement and quantum discord in the cavity QED models [PDF]
We investigate the quantum correlation between light and matter in bipartite quantum systems, drawing on the Jaynes–Cummings model and the Tavis–Cummings model, which are well-established in cavity quantum electrodynamics.

Analysis of Quantum Correlations Obtained Using Local Optimal Universal Asymmetric Cloners [PDF]
We apply the local optimal universal asymmetric cloning machine on an initially pure entangled state of two qubits. As output, we obtain two final states which present quantum correlations.

Quantum correlation in a nano-electro-optomechanical system enhanced by an optical parametric amplifier and Coulomb-type interaction [PDF]
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

Quantum feedback-enhanced discord in T-shaped plasmonic waveguides with embedded cavity [PDF]
This theoretical study presents a hybrid quantum system that combines the geometry of a T-shaped plasmonic waveguide with an embedded common cavity and applies quantum feedback control to enhance and preserve quantum discord between two quantum dots (QDs)

A new entropic quantum correlation measure for adversarial systems [PDF]
Quantum correlation often refers to correlations exhibited by two or more local subsystems under a suitable measurement. These correlations are beyond the framework of classical statistics and the associated classical probability distribution.

Quantum correlation of microwave two-mode squeezed state generated by nonlinearity of InP HEMT [PDF]
This study significantly concentrates on cryogenic InP HEMT high-frequency circuit analysis using quantum theory to find how the transistor nonlinearity can affect the quantum correlation of the modes generated.

Quantum correlations beyond entanglement in a classical-channel model of gravity [PDF]
A direct quantization of the Newtonian interaction between two masses is known to establish entanglement, which if detected would witness the quantum nature of the gravitational field.
