High-precision measurement of microwave electric field by cavity-enhanced critical behavior in a many-body Rydberg atomic system
Qinxia Wang, Yukang Liang, Zhihui Wang +5
It has been demonstrated that the Rydberg criticality in a many-body atomic system can enhance the measurement sensitivity of the microwave electric field by increasing the Fisher…
Enhancing the coherence time of a neutral atom by an optical quartic trap
Haobo Chang, Zhuangzhuang Tian, Xin Lv +7
The coherence time of an optically trapped neutral atom is a crucial parameter for quantum technologies. We found that optical dipole traps with higher-order spatial forms inherent…
Cavity-Enhanced Rydberg Atomic Superheterodyne Receiver
Yukang Liang, Qinxia Wang, Zhihui Wang +7
High-sensitivity measurements of the microwave electric field are important in applications of communication and metrology. \replaced{The sensitivity of traditional Rydberg superhe…
A cavity QED system with defect-free single-atom array strongly coupled to an optical cavity
Zhihui Wang, Shijun Guan, Guansheng Teng +4
We experimentally realize a new cavity quantum electrodynamics (QED) platform with defect-free single-atom array strongly coupled to an optical cavity. The defect-free single-atom…
