We report on the realization of a quantum sensor based on trapped atom interferometry in an optical lattice for the measurement of atom-surface interactions, with sub-micrometer-level control of the mean atom-surface separation distance. The force sensor reaches a short-term sensitivity of $3.4\times {10}^{-28}\mathrm{N}$ at 1 s and a long-term stability of 4 qN ($4\times {10}^{-30}\mathrm{N}$). We perform force measurements in the $0–300\mathrm{\mu }\mathrm{m}$ range, and despite significant stray forces caused by adsorbed atoms on the surface, we obtain evidence of the Casimir-Polder force.

我们报告了基于光学晶格中捕获原子干涉测量的量子传感器的实现，用于测量原子-表面相互作用，并对平均原子-表面间隔距离进行亚微米级控制。力传感器的短期灵敏度达到 $3.4\times {10}^{-28}\mathrm{N}$ 1 s 时的稳定性和 4 qN 的长期稳定性（ $4\times {10}^{-30}\mathrm{N}$ ）。我们进行力测量 $0–300\mathrm{\mu }\mathrm{m}$ 尽管表面上的吸附原子引起了显着的杂散力，但我们仍然获得了卡西米尔-波尔德力的证据。
