Concurrence of arbitrary dimensional bipartite quantum states
Kai Chen, Sergio Albeverio, Shao-Ming Fei
We derive an analytical lower bound for the concurrence of a bipartite quantum state in arbitrary dimension. A functional relation is established relating concurrence, the Peres-Ho…

Canonical Form and Separability of PPT States on Multiple Quantum Spaces
Xiao-Hong Wang, Shao-Ming Fei
By using the "subtracting projectors" method in proving the separability of PPT states on multiple quantum spaces, we derive a canonical form of PPT states in ${\Cb}^{K_1} \otimes…

On PPT States in KxMxN Composite Quantum Systems
Xiao-Hong Wang, Shao-Ming Fei, Zhi-Xi Wang +1
We study the general representations of positive partial transpose (PPT) states in . For the PPT states with rank- a canonical…
