Monotonicity of skew information and its applications in quantum resource theory
Weijing Li
We give an alternative proof of skew information via operator algebra approach and show its strong monotonicity under particular quantum TPCP maps. We then formulate a family of ne…

Geometric measures of discordlike quantum correlations based on Tsallis relative entropy
Weijing Li
In this paper we formulate a kind of new geometric measure of quantum correlations. This new measure is in terms of the quantum Tsallis relative entropy and can be viewed as a one-…
