摘要：
我们构建了一个可扩展的量子传感平台，该平台包含数百个可囚禁单个激光冷却原子的位点，并验证了这种单量子系统传感器阵列可应用于二维网格的磁场映射。每个原子被囚禁在面积为0.5平方微米的光镊中，原子间距为7.0(2)微米，由此实现了微米级空间分辨率与高度并行化运行。额外配备的可操控光镊可对网格内的原子进行重排，支持亚微米分辨率的单原子扫描显微成像。该单原子传感器平台可直接应用于外施直流梯度磁场的映射。在Ramsey型测量中，我们获得的磁场分辨率为98(29)纳特斯拉，估算灵敏度为25微特斯拉/赫兹的1/2次方。
英文摘要：
We implement a scalable platform for quantum sensing comprising hundreds of sites capable of holding individual laser-cooled atoms and demonstrate the applicability of this single-quantum-system sensor array to magnetic-field mapping on a two-dimensional grid. With each atom being confined in an optical tweezer within an area of 0.5 micrometer^2 at mutual separations of 7.0(2) micrometer, we obtain micrometer-scale spatial resolution and highly parallelized operation. An additional steerable optical tweezer allows for a rearrangement of atoms within the grid and enables single-atom scanning microscopy with sub-micron resolution. This individual-atom sensor platform finds its immediate application in mapping an externally applied DC gradient magnetic field. In a Ramsey-type measurement, we obtain a field resolution of 98(29) nanotesla. We estimate the sensitivity to 25 microtesla/Hz^1/2.
