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 …
Separability of rank two quantum states on multiple quantum spaces with different dimensions
Shao-Ming Fei, Xiu-Hong Gao, Xiao-Hong Wang +2
We consider the separability of rank two quantum states on multiple quantum spaces with different dimensions. The sufficient and necessary conditions for separability of these mult…
