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…
Complete Entanglement Witness for Quantum Teleportation
Ming-Jing Zhao, Shao-Ming Fei, Xianqing Li-Jost
We propose a set of linear quantum entanglement witnesses constituted by local quantum-mechanical observables with each two possible measurement outcomes. These witnesses detect al…
Equation of motion for multiqubit entanglement in multiple independent noisy channels
Zhong-Xiao Man, Yun-Jie Xia, Shao-Ming Fei
We investigate the possibility and conditions to factorize the entanglement evolution of a multiqubit system passing through multi-sided noisy channels. By means of a lower bound o…
