Entangled states with positive partial transpose arising from
indecomposable positive linear maps
Kil-Chan Ha, Seung-Hyeok Kye, Young Sung Park
abstract: We construct entangled states with positive partial transposes using
indecomposable positive linear maps between matrix algebras. We also exhibit
concrete examples of entangled states with positive partial transposes arising
in this way, and show that they generate extreme rays in the cone of all
positive semi-definite matrices with positive partial transposes. They also
have Schmidt numbers two.
