Assisted state discrimination without entanglement
Bo Li, Shao-Ming Fei, Zhi-Xi Wang +1
It is shown that the dissonance, a quantum correlation which is equal to quantum discord for separable state, is required for assisted optimal state discrimination. We find that on…
Nonlocality of two-qubit and three-qubit Schmidt-Correlated states
Ming-Jing Zhao, Zong-Guo Li, Bo Li +3
We investigate the nonlocality of Schmidt-correlated (SC) states, and present analytical expressions of the maximum violation value of Bell inequalities. It is shown that the viola…
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…
Faithful teleportation with arbitrary pure or mixed resource states
Ming-Jing Zhao, Zong-Guo Li, Shao-Ming Fei +2
We study faithful teleportation systematically with arbitrary entangled states as resources. The necessary conditions of mixed states to complete perfect teleportation are proved.…
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…
