A Note on Resistance of NPT to Mixture of Separable States

Bobo Hua, Xiu-Hong Gao, Ming-Jing Zhao +1

We study the stability of NPT property of an arbitrary pure entangled state under the mixture of arbitrary pure separable states. For bipartite pure states with Schmidt number …

Monogamous property of generalized W states in three-qubit systems in terms of relative entropy of entanglement

Zhen Wang, Xiu-Hong Gao, Zhi-Xi Wang

Because of the difficulty in getting the analytic formula of relative entropy of entanglement, it becomes troublesome to study the monogamy relations of relative entropy of entangl…

Lower Bound of Concurrence Based on Positive Maps

Xiao-Sheng Li, Xiu-Hong Gao, Shao-Ming Fei

We study the concurrence of arbitrary dimensional bipartite quantum systems. An explicit analytical lower bound of concurrence is obtained, which detects entanglement for some quan…

Lower Bounds of Concurrence for Tripartite Quantum Systems

Xiu-Hong Gao, Shao-Ming Fei, Ke Wu

We derive an analytical lower bound for the concurrence of tripartite quantum mixed states. A functional relation is established relating concurrence and the generalized partial tr…

Separability and entanglement in 2x3xN composite quantum systems

S. M. Fei, X. H. Gao, X. H. Wang +2

The separability and entanglement of quantum mixed states in $\Cb^2 \otimes \Cb^3 \otimes \Cb^N$ composite quantum systems are investigated. It is shown that all quantum states …
