Single-atom sensor for low-frequency electric field
Quan Yuan, Shuang-Qing Dai, Tai-Hao Cui +8
Precision measurement of low-frequency electric field (LFEF) signals with frequency from 30 kHz to 300 kHz is crucial for advancing both fundamental science and practical applicati…
Finite-Time Electrometry with a Quantum-Regime Single-Ion Phonon Laser
Pei-Dong Li, Yuan-Zhang Dong, Zhuo-Zhu Wu +6
The phonon laser realized in a trapped ion, i.e., a self-sustained mechanical oscillator, has demonstrated the unique characteristics in practically detecting externally applied el…
Experimental Witness of Quantum Jump Induced High-Order Liouvillian Exceptional Points
Zhuo-Zhu Wu, Pei-Dong Li, Tai-Hao Cui +11
The exceptional point has presented considerably interesting and counterintuitive phenomena associated with nonreciprocity, precision measurement, and topological dynamics. The Lio…
Chiral quantum heating and cooling with an optically controlled ion
Jin-Tao Bu, Jian-Qi Zhang, Ge-Yi Ding +12
Quantum heat engines and refrigerators are open quantum systems, whose dynamics can be well understood using a non-Hermitian formalism. A prominent feature of non-Hermiticity is th…
