Experimental Determination of Entanglement for Arbitrary Pure States
Shao-Ming Fei, Ming-Jing Zhao, Kai Chen +1
We present a way of experimentally determining the concurrence in terms of the expectation values of local observables for arbitrary multipartite pure states. In stead of the joint…
Multiqubits Entanglement Based on Optimal Witness
Ming-Jing Zhao, Zhi-Xi Wang, Shao-Ming Fei
We study the optimal entanglement witness with respect to multiqubits W-states. We show such entanglement witnesses can be used to distinguish genuine entangled states, different b…
A lower bound of concurrence for multipartite quantum states
Ming Li, Shao-Ming Fei, Zhi-XiWang
We study the concurrence of arbitrary multipartite mixed quantum states. An explicit lower bound of the concurrence is derived, which detects quantum entanglement of some states be…
