Practical robust Bayesian spin-squeezing-enhanced quantum sensing under noises
Jinye Wei, Jungeng Zhou, Yi Shen +2
Spin-squeezed states constitute a valuable entanglement resource capable of surpassing the standard quantum limit (SQL). However, spin-squeezed states only enable sub-SQL uncertain…
Symmetry-protected many-body Ramsey spectroscopy: precision scaling and robustness
Sijie Chen, Jiahao Huang, Min Zhuang +1
Quantum entanglement is a powerful quantum resource for enhancing measurement precision beyond classical limit. % Here we propose an entanglement-enhanced symmetry-protected destru…
Ramsey Spectroscopy via Symmetry-Protected Destructive Many-Body Interferometry
Sijie Chen, Jiahao Huang, Min Zhuang +1
Ramsey spectroscopy, a fundamental tool in both basic science and practical applications, is inevitably subject to several detrimental effects. % Here we propose a symmetry-protect…
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…
