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…

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…

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…
