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 $C^{K} \otimes C^{M} \otimes C^{N}$ . For the PPT states with rank- $N$ a canonical…

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…
