We realize a coherent transfer between a laser-accessible low-angular-momentum Rydberg state and the circular Rydberg level with maximal angular momentum. It is induced by a radio frequency field with a high-purity σ^{+} polarization resonant on Stark transitions inside the hydrogenic Rydberg manifold. We observe over a few microseconds more than 20 coherent Rabi oscillations between the initial Rydberg state and the circular level. We characterize these many-Rydberg-level oscillations and find them in perfect agreement with a simple model. This coherent transfer opens the way to hybrid quantum gates bridging the gap between optical communication and quantum information manipulations with microwave cavity and circuit quantum electrodynamics.
我们实现了在一个激光可及的低角动量里德堡态与具有最大角动量的圆里德堡能级之间的相干转移。它是由一个具有高纯度σ⁺极化的射频场诱导产生的，该射频场在氢里德堡流形内的斯塔克跃迁上共振。我们在几微秒内观测到初始里德堡态与圆能级之间有超过20次的相干拉比振荡。我们对这些多里德堡能级振荡进行了表征，并发现它们与一个简单模型完全吻合。这种相干转移为混合量子门开辟了道路，弥合了光通信与利用微波腔和电路量子电动力学进行量子信息操控之间的差距。
