Dynamics of quantum battery capacity under Markovian channels
Yao-Kun Wang, Li-Zhu Ge, Tinggui Zhang +2
We study the dynamics of the quantum battery capacity for the Bell-diagonal states under Markovian channels on the first subsystem. We show that the capacity increases for special…

One-Way Deficit and Holevo Quantity of Generalized -qubit Werner State
Yao-Kun Wang, Rui-Xin Chen, Li-Zhu Ge +2
Originated from the work extraction in quantum systems coupled to a heat bath, quantum deficit is a kind of significant quantum correlations like quantum entanglement. It links qua…

Maximal Holevo quantity based on weak measurements
Yao-Kun Wang, Shao-Ming Fei, Zhi-Xi Wang +2
The Holevo bound is a keystone in many applications of quantum information theory. We propose "weak maximal Holevo quantity" with weak measurements as the generalization of the sta…
