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…

Compact gravimeter with an ensemble of ultracold atoms in spin-dependent optical lattices
Yongguan Ke, Jiahao Huang, Min Zhuang +2
Atomic interferometry in optical lattices is a new trend of developing practical quantum gravimeter. Here, we propose a compact and portable gravimetry scheme with an ensemble of u…

Achieving Heisenberg-limited metrology with spin cat states via interaction-based readout
Jiahao Huang, Min Zhuang, Bo Lu +2
Spin cat states are promising candidates for quantum-enhanced measurement. Here, we analytically show that the ultimate measurement precision of spin cat states approaches the Heis…
