Rydberg atoms are remarkable tools for quantum simulation and computation. They are the focus of an intense experimental activity, mainly based on low-angular-momentum Rydberg states. Unfortunately, atomic motion and levels lifetime limit the experimental timescale to about $100\mu \mathrm{s}$. Here, we demonstrate two-dimensional laser trapping of long-lived circular Rydberg states for up to 10 ms. Our method is very general and opens many opportunities for quantum technologies with Rydberg atoms. The 10 ms trapping time corresponds to thousands of interaction cycles in a circular-state-based quantum simulator. It is also promising for quantum metrology and quantum information with Rydberg atoms, by bringing atom-field interaction times into unprecedented regimes.

圆形里德堡原子的激光陷印

Rydberg原子是用于量子模拟和计算的出色工具。它们是激烈实验活动的重点，主要是基于低角动量的里德堡状态。不幸的是，原子运动和能级寿命将实验时间限制在大约$100\mu \mathrm{s}$。在这里，我们演示了长达10 ms的长寿命圆形Rydberg态的二维激光陷波。我们的方法非常通用，为使用里德堡原子的量子技术打开了许多机会。10 ms的捕获时间对应于基于循环状态的量子模拟器中的数千个交互周期。通过将原子-场相互作用时间带入史无前例的领域，它对于利用里德堡原子进行量子计量和量子信息研究也很有前途。
