摘要

我们描述了一种在有限场(包括地球场)下工作的光泵原子梯度仪，其灵敏度为14 fT / Hz。我们证明了它在量子自旋噪声和原子扩散存在下的量子噪声限制行为。

A femtotesla quantum-noise-limited pulsed gradiometer at finite fields

We describe an optically pumped atomic gradiometer operating at finite fields, including Earth’s field, with 14 fT / Hz Hz sensitivity. We demonstrate its quantum-noise-limited behaviour in the presence of quantum spin noise and atomic diffusion.
