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…
