Quantum Locking of Intrinsic Spin Squeezed State in Earth-field-range Magnetometry
Peiyu Yang, Guzhi Bao, Jun Chen +3
In the Earth-field range, the nonlinear Zeeman (NLZ) effect has been a bottleneck limiting the sensitivity and accuracy of atomic magnetometry from physical mechanism. To break thi…
