Abstract

The use of hybrid atom-photon quantum systems takes advantage of the best features of the involved platforms: long storage times, fast processing capabilities, high quality entanglement and long-haul fiber transmission. Such properties are prerequisites for the implementation of a quantum communication network [1]. We report on a hybrid system composed of a photon-pair source, a quantum frequency converter, and a single trapped ion. The photon source is resonant with an atomic transition in the ion; the wavelength of one photon from the pair is translated to the telecommunications O-band by quantum frequency conversion; its detection heralds the absorption of the partner photon by the trapped ion.
