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…

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…
