Bipartite Bell Inequality and Maximal Violation
Ming Li, Shao-Ming Fei, Xianqing Li-Jost
We present new bell inequalities for arbitrary dimensional bipartite quantum systems. The maximal violation of the inequalities is computed. The Bell inequality is capable of detec…
Quantum Entanglement: Separability, Measure, Fidelity of Teleportation and Distillation
Ming Li, Shao-Ming Fei, Xianqing Li-Jost
Quantum entanglement plays crucial roles in quantum information processing. Quantum entangled states have become the key ingredient in the rapidly expanding field of quantum inform…
A Note on Quantum Entanglement and PPT
Shao-Ming Fei, Xianqing Li-Jost
We study quantum states for which the PPT criterion is both sufficient and necessary for separability. We present a class of 3x3 bipartite mixed states and show that these states a…
A Class of Bound Entangled States
Shao-Ming Fei, Xianqing Li-Jost, Bao-Zhi Sun
We construct a set of PPT (positive partial transpose) states and show that these PPT states are not separable, thus present a class of bound entangled quantum states.
