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…
Extending the coherence time limit of a single-alkali-atom qubit by suppressing phonon-jumping-induced decoherence
Zhuangzhuang Tian, Haobo Chang, Xin Lv +6
In the fields of quantum metrology and quantum information processing with the system of optically trapped single neutral atoms, the coherence time of qubit encoded in the electron…
Proposal of quantum repeater architecture based on Rydberg atom quantum processors
Yan-Lei Zhang, Qing-Xuan Jie, Ming Li +8
Realizing large-scale quantum networks requires the generation of high-fidelity quantum entanglement states between remote quantum nodes, a key resource for quantum communication,…
