We present programmable two-dimensional arrays of microscopic atomic ensembles consisting of more than 400 sites with nearly uniform filling and small atom number fluctuations. Our approach involves direct projection of light patterns from a digital micromirror device with high spatial resolution onto an optical pancake trap acting as a reservoir. This makes it possible to load large arrays of tweezers in a single step with high occupation numbers and low power requirements per tweezer. Each atomic ensemble is confined to ~1 μm³ with a controllable occupation from 20 to 200 atoms and with (sub)-Poissonian atom number fluctuations. Thus, they are ideally suited for quantum simulation and for realizing large arrays of collectively encoded Rydberg-atom qubits for quantum information processing.

我们介绍了微观原子团的可编程二维阵列，它由400多个位点组成，具有几乎均匀的填充和小的原子序数波动。我们的方法涉及将具有高空间分辨率的数字图案从数字微镜设备直接投影到充当储存器的光学薄饼陷阱上。这样就可以在一个步骤中以大占用数量和每个镊子低功率需求的单个步骤来装载大量镊子。每个原子合奏局限于〜1μm的³ 20到200个原子，并用（分）-Poissonian原子数涨落具有可控的职业。因此，它们非常适合于量子模拟和实现大集合的集体编码的里德堡原子量子位阵列，用于量子信息处理。
