Measurement-induced nonlocality based on the relative entropy
Zhengjun Xi, Xiaoguang Wang, Yongming Li
We quantify the measurement-induced nonlocality [Luo and Fu, Phys. Rev. Lett. 106, 120401 (2011)] from the perspective of the relative entropy. This quantification leads to an oper…
Necessary and sufficient condition for saturating the upper bound of quantum discord
Zhengjun Xi, Xiao-Ming Lu, Xiaoguang Wang +1
We revisit the upper bound of quantum discord given by the von Neumann entropy of the measured subsystem. Using the Koashi-Winter relation, we obtain a trade-off between the amount…
Pairwise Quantum Correlations for Superpositions of Dicke States
Zhengjun Xi, Heng-Na Xiong, Yongming Li +1
Pairwise correlation is really an important property for multi-qubit states. For the two-qubit X states extracted from Dicke states and their superposition states, we obtain a comp…
Influence of the Surface Structure and Vibration Mode on the Resistivity of Cu Films
Ya-Ni Zhao, Shi-Xian Qu, Ke Xia
The influence of the surface structure and vibration mode on the resistivity of Cu films and the corresponding size effect are investigated. The temperature dependent conductivitie…
Order continuous extensions of positive compact operators on Banach lattices
Jin Xi Chen, Zi Li Chen, Guo Xing Ji
Let and be Banach lattices. Let be a vector sublattice of and be an order continuous positive compact (resp. weakly compact) operators. We show…
