Bell inequalities for multipartite qubit quantum systems and their maximal violation
Ming Li, Shao-Ming Fei
We present a set of Bell inequalities for multiqubit quantum systems. These Bell inequalities are shown to be able to detect multiqubit entanglement better than previous Bell inequ…
Improved lower and upper bounds for entanglement of formation
Xue-Na Zhu, Shao-Ming Fei
We provide analytical lower and upper bounds for entanglement of formation for bipartite systems, which give a direct relation between the bounds of entanglement of formation and c…
Lower Bound of Multipartite Concurrence Based on Sub-quantum State Decomposition
Xue-Na Zhu, Ming-Jing Zhao, Shao-Ming Fei
We study the entanglement of tripartite quantum states and provide analytical lower bound of concurrence in terms of the concurrence of sub-states. The lower bound may improve all…
Local Unitary Equivalence of Arbitrary Dimensional Bipartite Mixed Quantum States
Chunqin Zhou, Tinggui Zhang, Shao-Ming Fei +2
The nonlocal properties of arbitrary dimensional bipartite quantum systems are investigated. A complete set of invariants under local unitary transformations is presented. These in…
