Journal ArticleDOI
Almost all quantum states have nonclassical correlations
TL;DR: In this paper, it was shown that positive-discord states are negligible in the whole Hilbert space and that an arbitrary Markovian evolution cannot lead to a sudden, permanent vanishing of discord.
Journal ArticleDOI
Quantum steering: A review with focus on semidefinite programming
TL;DR: In this article, the authors give an overview of how to characterise quantum steering through semidefinite programming and provide efficient numerical methods to address a number of problems, including steering detection, quantification, and applications.
Journal ArticleDOI
Quantifying Einstein-Podolsky-Rosen Steering
TL;DR: It is shown that every pure entangled state is maximally steerable and the projector onto the antisymmetric subspace is maximALLY steerable for all dimensions; a new example of one-way steering is provided and strong support is given that states with positive-partial transposition are not steerable.
Journal ArticleDOI
Operational interpretations of quantum discord
Daniel Cavalcanti,Leandro Aolita,Sergio Boixo,Kavan Modi,Marco Piani,Andreas Winter,Andreas Winter +6 more
TL;DR: In this paper, the authors give quantum discord its first information-theoretic operational meaning in terms of entanglement consumption in an extended quantum-state-merging protocol and further relate the asymmetry of quantum discord with the performance imbalance in quantum state merging and dense coding.
Journal ArticleDOI
Inequivalence of entanglement, steering, and Bell nonlocality for general measurements
Marco Túlio Quintino,Tamás Vértesi,Tamás Vértesi,Daniel Cavalcanti,Remigiusz Augusiak,Maciej Demianowicz,Antonio Acín,Nicolas Brunner +7 more
TL;DR: In this paper, it was shown that entanglement, one-way steering, two-way and non-localization are genuinely different considering general measurements, i.e., single round positive-operator-valued measures.
