Identification of Unentangled–Entangled Border in the Luttinger Liquid Phase
Crystals, 2019 Quantum discord and entanglement are both criteria for distinguishing quantum correlations in a quantum system. We studied the effect of the transverse magnetic field on the quantum discord of the one-dimensional spin-1/2 XX model.

Channel discord and distortion
New Journal of Physics, 2021 Discord, originally notable as a signature of bipartite quantum correlation, in fact can be nonzero classically, i.e. arising from noisy measurements by one of the two parties.

Experimental Investigation of the Evolution of Gaussian Quantum Discord in an Open System [PDF]
, 2012 Gaussian quantum discord is a measure of quantum correlations in Gaussian systems. Using Gaussian discord we quantify the quantum correlations of a bipartite entangled state and a separable two-mode mixture of coherent states.

IEEE Photonics Journal, 2018 We investigate the decay properties of the quantumness including quantum entanglement, quantum discord, and quantum coherence for two photonic qubits, which are partially entangled in their orbital angular momenta, through Kolmogorov turbulent atmosphere.

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 ...

Analytic Expression of Quantum Discords in Werner States under LQCC
Entropy, 2020 In this paper, quantum discords in a special kind of states, i.e., Werner states by local quantum operations and classical communication (LQCC) protocols (WLQCC states), are studied.
