Single neutral atoms trapped in optical tweezers and laser-coupled to Rydberg states provide a fast and flexible platform to generate configurable atomic arrays for quantum simulation. The platform is especially suited to study quantum spin systems in various geometries. However, for experiments requiring continuous trapping, inhomogeneous light shifts induced by the trapping potential and temperature broadening impose severe limitations. Here we show how Raman sideband cooling allows one to overcome those limitations, thus, preparing the stage for Rydberg dressing in tweezer arrays.

光学镊子阵列中的拉曼边带冷却，用于里德伯格敷料

捕获在光镊中并激光耦合到Rydberg态的单个中性原子提供了一个快速而灵活的平台，可以为量子模拟生成可配置的原子阵列。该平台特别适合研究各种几何形状的量子自旋系统。但是，对于需要连续捕获的实验，由捕获势和温度范围扩大引起的不均匀的光偏移强加了限制。在这里，我们展示了拉曼边带冷却如何使人们克服这些限制，从而为镊子阵列中的里德伯格修整做好准备。
