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…
Nonreciprocal Entanglement by Dynamically Encircling a Nexus
Lei Huang, Peng-Fei Wang, Jian-Qi Zhang +5
Nonreciprocal entanglement, characterized by inherently robust operation, is a cornerstone for quantum information processing and communications. However, it remains a great challe…
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…
