Separability of Tripartite Quantum Systems
Ming Li, Shao-Ming Fei, Zhi-Xi Wang
We investigate the separability of arbitrary dimensional tripartite sys- tems. By introducing a new operator related to transformations on the subsystems a necessary condition for…

Representation Class and Geometrical Invariants of Quantum States under Local Unitary Transformations
Zu-Huan Yu, Xian-Qing Li-Jost, Shao-Ming Fei
We investigate the equivalence of bipartite quantum mixed states under local unitary transformations by introducing representation classes from a geometrical approach. It is shown…
