Adaptive cold-atom magnetometry mitigating the trade-off between sensitivity and dynamic range
Zhu Ma, Chengyin Han, Zhi Tan +7
Cold-atom magnetometers can achieve an exceptional combination of superior sensitivity and high spatial resolution. One key challenge these quantum sensors face is improving the se…
Credible-interval-based adaptive Bayesian quantum frequency estimation for entanglement-enhanced atomic clocks
Jungeng Zhou, Jiahao Huang, Jinye Wei +2
Entanglement-enhanced quantum sensors encounter a fundamental trade-off: while entanglement improves precision to the Heisenberg limit, it restricts dynamic range. To address this…
Image enhancement algorithm for absorption imaging
Pengcheng Zheng, Songqian Zhang, Zhu Ma +7
The noise in absorption imaging of cold atoms significantly impacts measurement accuracy across a range of applications with ultracold atoms. It is crucial to adopt an approach tha…
Atomic clock locking with Bayesian quantum parameter estimation: scheme and experiment
Chengyin Han, Zhu Ma, Yuxiang Qiu +7
Atomic clocks are crucial for science and technology, but their sensitivity is often restricted by the standard quantum limit. To surpass this limit, correlations between particles…
Quantum Double Lock-in Amplifier
Sijie Chen, Min Zhuang, Ruihuang Fang +5
Quantum lock-in amplifier aims to extract an alternating signal within strong noise background by using quantum strategy. However, as the target signal usually has an unknown initi…
Temporal Spinwave Fabry-Perot Interferometry via Coherent Population Trapping
Ruihuan Fang, Chengyin Han, Xunda Jiang +6
Ramsey spectroscopy via coherent population trapping (CPT) is essential in precision measurements. The conventional CPT-Ramsey fringes contain numbers of almost identical oscillati…
