A new approach for the realization of a quantum interface between single photons and single ions in an ion crystal is proposed and analyzed. In our approach the coupling between a single photon and a single ion is enhanced via the collective degrees of freedom of the ion crystal. Applications including single-photon generation, a memory for a quantum repeater, and a deterministic photon-photon, photon-phonon, or photon-ion entangler are discussed.
提出并分析了一种在离子晶体中实现单光子和单离子之间量子接口的新方法。在我们的方法中,通过离子晶体的集体自由度增强了单光子和单离子之间的耦合。讨论了包括单光子产生、量子中继器存储器以及确定性光子-光子、光子-声子或光子-离子纠缠器在内的应用。
