Polygamy relation of quantum correlations with equality

Zhi-Xiang Jin, Bing Yu, Xue-Na Zhu +2

We provide a generalized definition of polygamy relations for any quantum correlation measures. Instead of the usual polygamy inequality, a polygamy relation with equality is given…

Monogamy of entanglement for tripartite systems

Xue-Na Zhu, Gui Bao, Zhi-Xiang Jin +1

We study the monogamy of arbitrary quantum entanglement measures for tripartite quantum systems. Both sufficient and necessary conditions for to be monogamous in terms of t…

A Family of Bipartite Separability Criteria Based on Bloch Representation of Density Matrices

Xue-Na Zhu, Jing Wang, Gui Bao +3

We study the separability of bipartite quantum systems in arbitrary dimensions based on the Bloch representation of density matrices. We present two separability criteria for quant…

Edge state, bound state and anomalous dynamics in the Aubry-André-Haper system coupled to non-Markovian baths

H. T. Cui, H. Z. Shen, M. Qin +1

Bound states and their influence on the dynamics of an one-dimensional tight-binding system subject to environments are studied in this paper. We identify specifically three kinds…

Quantifying quantum coherence based on the generalized relative Rnyi entropy

Xue-Na Zhu, Zhi-Xiang Jin, Shao-Ming Fei

We present a family of coherence quantifiers based on the generalized relative Rnyi entropy. These quantifiers satisfy all the standard criteria for well-defined m…

A lower bound of concurrence for multipartite quantum systems

Xue-Na Zhu, Ming Li, Shao-Ming Fei

We present a lower bound of concurrence for four-partite systems in terms of the concurrence for part quantum systems and give an analytical lower bound for $…
