Inequalities Detecting Quantum Entanglement for Systems
Ming-Jing Zhao, Teng Ma, Shao-Ming Fei +1
We present a set of inequalities for detecting quantum entanglement of quantum states. For and systems, the inequalities give rise to suffici…
Photon Induced Entanglement in Atom-Cavity Systems
Li-Li Lan, Xiang-Bin Wang, Shao-Ming Fei
We study the evolution of quantum entanglement in double cavity systems. The entanglement of cavity atoms induced by entangled pair of photons is investigated. Both entanglement su…
Quantum discord and geometry for a class of two-qubit states
Bo Li, Zhi-Xi Wang, Shao-Ming Fei
We study the level surfaces of quantum discord for a class of two-qubit states with parallel nonzero Bloch vectors. The dynamic behavior of quantum discord under decoherence is inv…
Lower Bound of Concurrence Based on Positive Maps
Xiao-Sheng Li, Xiu-Hong Gao, Shao-Ming Fei
We study the concurrence of arbitrary dimensional bipartite quantum systems. An explicit analytical lower bound of concurrence is obtained, which detects entanglement for some quan…
Local unitary equivalent consistence for n-party states and their (n-1)-party reduced density matrices
Zhen Wang, He-Ping Wang, Zhi-Xi Wang +1
We present that the local unitary equivalence of n-party pure states is consistent with the one of their (n-1)-party reduced density matrices. As an application, we obtain the loca…
Scalar products of the open XYZ chain with non-diagonal boundary terms
Wen-Li Yang, Xi Chen, Jun Feng +4
With the help of the F-basis provided by the Drinfeld twist or factorizing F-matrix of the eight-vertex solid-on-solid (SOS) model, we obtain the determinant representations of the…
