Entanglement and work extraction in the central-spin quantum battery
Jia-Xuan Liu, Hai-Long Shi, Yun-Hao Shi +2
We consider a central-spin battery where central spins serve as battery cells and bath spins serve as charging units. It is shown that the energy stored in the battery…
A Necessary and Sufficient Entanglement Criterion of N-qubit System Based on Correlation Tensor
Feng-Lin Wu, Si-Yuan Liu, Wen-Li Yang +2
Great advances have been achieved in studying characteristics of entanglement for fundamentals of quantum mechanics and quantum information processing. However, even for N-qubit sy…
Entanglement, Coherence, and Extractable Work in Quantum Batteries
Hai-Long Shi, Shu Ding, Qing-Kun Wan +2
We investigate the connection between quantum resources and extractable work in quantum batteries. We demonstrate that quantum coherence in the battery or the battery-charger entan…
Testing quantum entanglement with local measurement
Qing Xie, X. -X. Wu, X. -M. Ding +3
We propose to detect quantum entanglement by a condition of local measurments. We find that this condition can detect efficiently the pure entangled states for both discrete and co…
