Superconducting transmon qubit-resonator quantum battery
Fu-Quan Dou, Fang-Mei Yang
Quantum battery (QB) is the miniature energy storage and release device and plays a crucial role in future quantum technology. Here, an implementation scheme of a QB is proposed on…
Fast charging of Lipkin-Meshkov-Glick quantum battery
Cheng-Jie Wang, Yuan-Jin Wang, Fu-Quan Dou
Fast charging is a pivotal and fundamental performance metric in quantum battery (QB) research. Here, we investigate the fast-charging performance of the Lipkin-Meshkov-Glick QB ba…
Quantum Speed Limit under Brachistochrone Evolution
Fu-Quan Dou, Min-Peng Han, Chuan-Cun Shu
According to the Heisenberg uncertainty principle between time and energy fluctuation, a concept of the quantum speed limit (QSL) has been established to determine the minimum evol…
Cavity-Heisenberg spin chain quantum battery
Fu-Quan Dou, Hang Zhou, Jian-An Sun
We propose a cavity-Heisenberg spin chain (CHS) quantum battery (QB) with the long-range interactions and investigate its charging process. The performance of the CHS QB is substan…
Controllable multiple beam splitting in Hermitian and non-Hermitian symmetric coupled waveguide systems
Fu-Quan Dou, Ya-Ting Wei, Min-Peng Han +1
We investigate high-fidelity multiple beam splitting in Hermitian and non-Hermitian symmetric coupled waveguides with one input and 2N output waveguide channels. In Hermitian syste…
