我们提出了一个组合的捕获离子和光学腔系统的实现，其中一个单一的Yb+离子被限制在一个230 μ m长的光纤腔中的微米级离子阱。我们描述了空间离子腔耦合和测量的离子腔耦合强度使用腔刺激的λ跃迁。由于光纤谐振腔的模体积小，离子和单个光子之间的相干耦合强度超过了偶极矩的自然衰减率。该系统可以集成到离子-光子量子网络中，是实现基于腔量子电动力学的囚禁离子量子信息处理的一步。DOI：10.1103/PhysRevLett.110.043003
We present the realization of a combined trapped-ion and optical cavity system, in which a single Yb+ ion is confined by a micron-scale ion trap inside a 230 mu m-long optical fiber cavity. We characterize the spatial ion-cavity coupling and measure the ion-cavity coupling strength using a cavity-stimulated Lambda transition. Owing to the small mode volume of the fiber resonator, the coherent coupling strength between the ion and a single photon exceeds the natural decay rate of the dipole moment. This system can be integrated into ion-photon quantum networks and is a step towards cavity quantum electrodynamics based quantum information processing with trapped ions.
