Optimal energy storage in the Tavis-Cummings quantum battery
Hui-Yu Yang, Hai-Long Shi, Qing-Kun Wan +3
The Tavis-Cummings (TC) model, which serves as a natural physical realization of a quantum battery, comprises atoms as battery cells that collectively interact with a shared…
Quantum-Enhanced Metrology in Cavity Magnomechanics
Qing-Kun Wan, Hai-Long Shi, Xi-Wen Guan
Magnons, as fundamental quasiparticles emerged in elementary spin excitations, hold a big promise for innovating quantum technologies in information coding and processing. Here we…
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…
Decoherence dynamics of entangled quantum states in the central spin model
Qing-Kun Wan, Hai-Long Shi, Xu Zhou +2
Maintaining coherence of a qubit is of vital importance for realizing a large-scale quantum computer in practice. In this work, we study the central spin decoherence problem in the…
