Programmable atom-photon quantum interface

Abstract

We present the implementation of a programmable atom-photon quantum interface, employing a single trapped ${}^{40}$Ca${}^{+}$ ion and single photons. Depending on its mode of operation, the interface serves as a bi-directional atom-photon quantum-state converter, as a source of entangled atom-photon states, or as a quantum frequency converter of single photons. The interface lends itself particularly to interfacing ions with single or entangled photons in hybrid quantum networks.
