Differential Geometry of Bipartite Quantum States
Zuhuan Yu, Xianqing Jost-Li, Qingzhong Li +2
We investigate the differential geometry of bipartite quantum states. In particular the manifold structures of pure bipartite states are studied in detail. The manifolds with respe…
Local Equivalence of Rank-Two Quantum Mixed States
Sergio Albeverio, Shao-Ming Fei, Debashish Goswami
We investigate the equivalence of quantum mixed states under local unitary transformations. For a class of rank-two mixed states, a sufficient and necessary condition of local equi…
Concurrence and a proper monogamy inequality for arbitrary quantum states
Yong-Cheng Ou, Heng Fan, Shao-Ming Fei
We obtain an analytical lower bound of entanglement quantified by concurrence for arbitrary bipartite quantum states. It is shown that our bound is tight for some mixed states and…
Addendum to "Multipartite states under local unitary transformations"
Sergio Albeverio, Laura Cattaneo, Shao-Ming Fei +1
In previous work the authors introduced a notion of generic states and obtained criteria for local equivalence of them. Here they introduce the concept of CHG states maintaining th…
A Note on Pseudo-Hermitian Systems with Point Interactions and Quantum Separability
Shao-Ming Fei
We study the quantum entanglement and separability of Hermitian and pseudo-Hermitian systems of identical bosonic or fermionic particles with point interactions. The separability c…
Entanglement conditions for multi-mode states
Zong-Guo Li, Shao-Ming Fei, Zhi-Xi Wang +1
We provide a class of inequalities for detecting entanglements in multi-mode systems. Necessary conditions for fully separable, bi-separable and sufficient conditions for fully ent…
