Single-atom sensor for low-frequency electric field
Quan Yuan, Shuang-Qing Dai, Tai-Hao Cui +8
Precision measurement of low-frequency electric field (LFEF) signals with frequency from 30 kHz to 300 kHz is crucial for advancing both fundamental science and practical applicati…

Enhanced detection of electric field signals via squeezing-induced stochastic resonance
Ya-Qi Wei, Tai-Hao Cui, Quan Yuan +10
Stochastic resonance (SR) could amplify weak electric-field signals in nonlinear systems by means of the externally injected noises. Here we propose and experimentally demonstrate…
