We demonstrate three-dimensional trapping of individual Rydberg atoms in holographic optical bottle beam traps. Starting with cold, ground-state ^{87}Rb atoms held in standard optical tweezers, we excite them to nS_{1/2}, nP_{1/2}, or nD_{3/2} Rydberg states and transfer them to a hollow trap at 850 nm. For principal quantum numbers 60≤n≤90, the measured trapping time coincides with the Rydberg state lifetime in a 300 K environment. We show that these traps are compatible with quantum information and simulation tasks by performing single qubit microwave Rabi flopping, as well as by measuring the interaction-induced, coherent spin-exchange dynamics between two trapped Rydberg atoms separated by 40  μm. These results will find applications in the realization of high-fidelity quantum simulations and quantum logic operations with Rydberg atoms.

汽化瓶形束阱中单个里德堡原子的三维陷阱。

我们展示了全息光学瓶光束陷阱中的单个里德伯格原子的三维陷阱。从保持在标准光学镊子中的冷基态^ {87} Rb原子开始，我们将其激发到nS_ {1/2}，nP_ {1/2}或nD_ {3/2} Rydberg态并将它们转移到850 nm处的中空陷阱。对于60≤n≤90的主量子数，测得的俘获时间与300 K环境中的里德堡态寿命一致。我们通过执行单个量子位微波拉比翻转以及通过测量由40μm隔开的两个被捕获的里德堡原子之间的相互作用诱导的，相干的自旋交换动力学，表明这些陷阱与量子信息和模拟任务兼容。这些结果将在利用Rydberg原子实现高保真量子模拟和量子逻辑运算中找到应用。
