Canonical Form and Separability of PPT States in 2xMxN Composite Quantum Systems

X. H. Wang, S. M. Fei, Z. X. Wang +1

We investigate the canonical forms of positive partial transposition (PPT) density matrices in ${\mathcal{C}}^2\otimes {\mathcal{C}}^M\otimes {\mathcal{C}}^N$ composite quantum systems with ran…
