Classification of bi-qutrit PPT entangled edge states by their ranks    [PDF]

Seung-Hyeok Kte, Hiroyuki Osaka

We construct $3\otimes 3$ PPT entangled edge states with maximal ranks, to
complete the classification of $3\otimes 3$ PPT entangled edge states by their
types. The ranks of the states and their partial transposes are 8 and 6,
respectively. These examples also disprove claims in the literature.
