Measuring quantum discord at the LHC
Journal of High Energy PhysicsThere has been an increasing interest in exploring quantities associated with quantum information at colliders. We perform a detailed analysis describing how to measure the quantum discord in the top anti-top quantum state at the Large Hadron Collider ...

The tripartite quantum-memory-assisted entropic uncertainty relation and upper bound on shareability of quantum discord [PDF]
Scientific Reports, 2022 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.

Entanglement and quantum discord in the cavity QED models [PDF]
HeliyonWe 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.

Quantum Discord, Thermal Discord, and Entropy Generation in the Minimum Error Discrimination Strategy [PDF]
Entropy, 2019 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.

Revealing Tripartite Quantum Discord with Tripartite Information Diagram
Entropy, 2017 A new measure based on the tripartite information diagram is proposed for identifying quantum discord in tripartite systems. The proposed measure generalizes the mutual information underlying discord from bipartite to tripartite systems, and utilizes ...

Interpreting quantum discord in quantum metrology [PDF]
Journal of Physics: Conference Series, 2015 Multipartite quantum systems show properties which do not admit a classical explanation. In particular, even nonentangled states can enjoy a kind of quantum correlations called quantum discord. I discuss some recent results on the role of quantum discord in metrology. Given an interferometric phase estimation protocol where the Hamiltonian is initially

QUANTUM DISCORD AS A RESOURCE IN QUANTUM COMMUNICATION [PDF]
International Journal of Modern Physics B, 2012 As quantum technologies move from the issues of principle to those of practice, it is important to understand the limitations on attaining tangible quantum advantages. In the realm of quantum communication, quantum discord captures the damaging effects of a decoherent environment.

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
