Correlations Between Quantum Battery Capacity and Quantum Resources for Two-qubit System
Yiding Wang, Xiaofen Huang, Tinggui Zhang
We investigate the relationship between quantum battery capacity and quantum resources in a two-qubit system consisting of mutually coupled battery and charger subsystems. We find…
Trade-off relations and enhancement protocol of quantum battery capacities in multipartite systems
Yiding Wang, Xiaofen Huang, Shao-Ming Fei +1
First, we investigate the trade-off relations of quantum battery capacities in two-qubit system. We find that the sum of subsystem battery capacity is governed by the total system…
Notes on detection and measurement of quantum coherence
Yiding Wang, Tinggui Zhang
Quantum coherence is one of the most basic characteristics of quantum mechanics. Here we give some methods to detect and measure quantum coherence. Firstly, we propose a coherence…
Improving Quantum Battery Capacity in Tripartite Quantum Systems by Local Projective Measurements
Yiding Wang, Hui Liu, Shao-Ming Fei +1
The impact of local von Neumann measurements on quantum battery capacity is investigated in tripartite quantum systems. Two measurement-based protocols are proposed and the concept…
Quantifying quantum-state texture
Yiding Wang, Hui Liu, Tinggui Zhang
Quantum-state texture is a newly recognized quantum resource that has garnered attention with the advancement of quantum theory. In this work, we introduce several potential quantu…
Witness based nonlinear detection of quantum entanglement
Yiding Wang, Tinggui Zhang, Xiaofen Huang +1
We present a nonlinear entanglement detection strategy which detects entanglement that the linear detection strategy fails. We show that when the nonlinear entanglement detection s…
