Quantum dynamic response-based NV-diamond magnetometry: Robustness to decoherence and applications in motion detection of magnetic nanoparticles
Wenkui Ding, Xingyu Zhang, Jing Liu +1
We propose a novel quantum sensing protocol that leverages the dynamical response of physical observables to quenches in quantum systems. Specifically, we use the nitrogen-vacancy…
Optimal state for a Tavis-Cummings quantum battery via the Bethe ansatz method
Wangjun Lu, Jie Chen, Le-Man Kuang +1
In this paper, we investigate the effect of different optical field initial states on the performance of the Tavis-Cummings (T-C) quantum battery. In solving the dynamical evolutio…
Influence of kinetic energy on the metrology of Rabi frequency
Xingyu Zhang, Xiaoguang Wang
The interacting model describing the Rabi transition is essential in studying atom-photon interactions, where the kinetic energy term is often neglected for the convenience of anal…
Charging of quantum batteries with general harmonic power
Jie Chen, Liyao Zhan, Lei Shao +3
We analyse the charging process of quantum batteries with general harmonic power. To describe the charge efficiency, we introduce the charge saturation and the charging power, and…
