Abstract:
The definition of quantum states with strong positive partial transpose (SPPT) in bipartite systems was presented in Phys. Rev. A 77, 022113, 2008 and the separability of super SPPT was studied in J. Phys. A: Math. Theor. 46, 205303, 2013. We generalize the definition of SPPT to tripartite quantum systems and study the separability of super SPPT in tripartite systems. We present that super SPPT states are bi-separable in 2 aSu 2 aSu N systems. Then a sufficient condition for fully separability of super SPPT states and a separable decomposition for any of these states are derived. Moreover, we generalize the results of 2 aSu 2 aSu N systems to the case of N (1) aSu N (2) aSu N (3) systems.
