Abstract
We present the realization of a combined trapped-ion and optical cavity system, in which a single ion is confined by a micron-scale ion trap inside a -long optical fiber cavity. We characterize the spatial ion-cavity coupling and measure the ion-cavity coupling strength using a cavity-stimulated 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.

Optical Fibers Illuminate Single Ion
Published 25 January 2013
A tiny cavity made from two optical fibers—previously used only with neutral atoms—strengthens the interaction between an ion and a photon, an important step toward quantum computers and networks.
