Quantum discord and its allies: a review of recent progress

A Bera, T Das, D Sadhukhan, SS Roy… - Reports on Progress …, 2017‏ - iopscience.iop.org
We review concepts and methods associated with quantum discord and related topics. We
also describe their possible connections with other aspects of quantum information and …

Measures and applications of quantum correlations

G Adesso, TR Bromley… - Journal of Physics A …, 2016‏ - iopscience.iop.org
Quantum information theory is built upon the realisation that quantum resources like
coherence and entanglement can be exploited for novel or enhanced ways of transmitting …

Constructive feedback of non-Markovianity on resources in random quantum states

R Gupta, S Gupta, S Mal, A Sen - Physical Review A, 2022‏ - APS
We explore the impact of non-Markovian channels on the quantum correlations of Haar
uniformly generated random two-qubit input states with different ranks: Either one of the …

The aspect of bipartite coherence in quantum discord to semi-device-independent nonlocality and its implication for quantum information processing

C Jebarathinam, HY Ku, HC Cheng… - arxiv preprint arxiv …, 2024‏ - arxiv.org
Quantum discord can demonstrate quantum nonlocality in the context of a semi-device-
independent Bell or steering scenario, ie, by assuming only the Hilbert-space dimension …

Phonon-mediated generation of quantum correlations between quantum dot qubits

J Krzywda, K Roszak - Scientific reports, 2016‏ - nature.com
We study the generation of quantum correlations between two excitonic quantum dot qubits
due to their interaction with the same phonon environment. Such generation results from the …

Remote state preparation using correlations beyond discord

S Kanjilal, A Khan, C Jebarathinam, D Home - Physical Review A, 2018‏ - APS
In recent years, exploration of the possible use of separable states as a resource to achieve
quantum information processing (QIP) tasks has been gaining increasing significance. In …

The relation between the quantum discord and quantum teleportation: The physical interpretation of the transition point between different quantum discord decay …

K Roszak - Europhysics Letters, 2015‏ - iopscience.iop.org
We study quantum teleportation via Bell-diagonal mixed states of two qubits in the context of
the intrinsic properties of the quantum discord. We show that when the quantum-correlated …

Separable states improve protocols with finite randomness

TKC Bobby, T Paterek - New Journal of Physics, 2014‏ - iopscience.iop.org
It is known from Bellʼs theorem that quantum predictions for some entangled states cannot
be mimicked using local hidden variable (LHV) models. From a computer science …

Excessive distribution of quantum entanglement

M Zuppardo, T Krisnanda, T Paterek… - Physical Review A, 2016‏ - APS
We classify entanglement distribution protocols based on whether or not entanglement gain
is observed with respect to communicated and initial entanglement. We call a protocol …

Limits for entanglement distribution with separable states

A Streltsov, H Kampermann, D Bruß - Physical Review A, 2014‏ - APS
Entanglement distribution with separable states has recently attracted considerable
attention. Recent results suggest that quantum discord, a measure for quantum correlations …
