Loschmidt Echo and Berry phase of the quantum system coupled to the XY spin chain: Proximity to quantum phase transition
Zi-Gang Yuan, Ping Zhang, Shu-Shen Li
We study the Loschmidt echo (LE) of a coupled system consisting of a central spin and its surrounding environment described by a general XY spin-chain model. The quantum dynamics o…

Detecting a set of entanglement measures in an unknown tripartite quantum state by local operations and classical communication
Yan-Kui Bai, Shu-Shen Li, Hou-Zhi Zheng +1
We propose a more general method for detecting a set of entanglement measures, i.e. negativities, in an \emph{arbitrary} tripartite quantum state by local operations and classical…
