Dynamics of quantum discord of two coupled spin-1/2’s subjected to time-dependent magnetic fields [PDF]
Results in Physics, 2019 We describe the dynamics of quantum discord of two interacting spin-1/2’s subjected to controllable time-dependent magnetic fields. The exact time evolution of discord is given for various input mixed states consisting of classical mixtures of two Bell ...

Maximizing quantum discord from interference in multi-port fiber beamsplitters
npj Quantum Information, 2021 Fourth-order interference is an information processing primitive for photonic quantum technologies, as it forms the basis of photonic controlled-logic gates, entangling measurements, and can be used to produce quantum correlations.

Effective detection of quantum discord by using Convolutional Neural Networks [PDF]
Quantum Machine IntelligenceQuantum discord represents a type of correlation defined as the difference between quantum and classical mutual information of two parties. Due to the optimization involved in the definition of classical mutual information of quantum systems, calculating

Quantum correlations beyond entanglement in a classical-channel model of gravity [PDF]
Scientific Reports, 2022 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.

Remote transfer of Gaussian quantum discord
Optics Express, 2014 Quantum discord quantifies quantum correlation between quantum systems, which has potential application in quantum information processing. In this paper, we propose a scheme realizing the remote transfer of Gaussian quantum discord, in which another ...
