Quantum features of gravcats [PDF]
Scientific ReportsWe explore the quantum features of two gravitational cats (gravcats) modeled by two qubits, focusing on quantum steerability, concurrence, and geometric quantum discord under varying conditions of gravitational interaction strength, temperature, and ...

Quantum discord: ‘discord’ between the whole and its constituent [PDF]
Journal of Physics A: Mathematical and Theoretical, 2012 Quantum discord, a measure of quantum correlation beyond entanglement, is initially defined as the discord between two classically equivalent while quantum discordant definitions of mutual information. In this paper, we report some new interpretations of discord which rely on the differences between measurement induced effects on the local measured ...

Global Quantum Discord in Multipartite Systems [PDF]
Physical Review A, 2011 We propose a global measure for quantum correlations in multipartite systems, which is obtained by suitably recasting the quantum discord in terms of relative entropy and local von Neumann measurements.

Quantum Discord and Steering in Top Quarks at the LHC. [PDF]
Physical Review Letters, 2022 Top quarks have been recently shown to be a promising system to study quantum information at the highest-energy scale available. The current lines of research mostly discuss topics such as entanglement, Bell nonlocality or quantum tomography.

Geometric quantum discord and coherence in a dipolar interacting magnetic system [PDF]
Physica Scripta, 2023 The study of low-dimensional metal complexes has revealed fascinating characteristics regarding the ground-state crossover shown by spin-gaped systems. In this context, this work explores the effect of the quantum-level crossing, induced by the magnetic ...

Efficient Characterization of Quantum Evolutions via a Recommender System [PDF]
Quantum, 2021 We demonstrate characterizing quantum evolutions via matrix factorization algorithm, a particular type of the recommender system (RS). A system undergoing a quantum evolution can be characterized in several ways.

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.
