MiS Preprint Repository
We have decided to discontinue the publication of preprints on our preprint server end of 2024. The publication culture within mathematics has changed so much due to the rise of repositories such as ArXiV (www.arxiv.org) that we are encouraging all institute members to make their preprints available there. An institute's repository in its previous form is, therefore, unnecessary. The preprints published to date will remain available here, but we will not add any new preprints here.
Uniform Quantification of Correlations for Bipartite Systems
Ting-Gui Zhang, Hong Yang, Xianqing Li-Jost and Shao-Ming FeiAbstract
Based on the relative entropy, we give a unified characterization of quantum correlations for nonlocality, steerability, discord and entanglement for any bipartite quantum states. For two-qubit states we show that the quantities obtained from quantifying nonlocality, steerabiity, entanglement and discord have strictly monotonic relationship. As for examples, the Bell diagonal states are studied in detail.
