Abstract

We give a canonical form of PPT states in C 2 ⊗ C 2 ⊗ C 2 ⊗ C N with rank=N. From this canonical form a sufficient separability condition for these states is presented.

We investigate the canonical forms of positive partial transposition (PPT) density matrices in ${\cal C}^2 \otimes {\cal C}^M \otimes {\cal C}^N$ composite quantum systems with rank $N$. A general expression for these PPT states are explicitly obtained. From this canonical form a sufficient separability condition is presented.

CANONICAL FORM AND SEPARABILITY OF PPT STATES ON MULTIPLE QUANTUM SPACES
