Achieving Hong-Ou-Mandel Interference Between a trapped ion and Rydberg ensemble
Abstract
Future efforts to build quantum networks are likely to rely on the ability to interface and entangle disparate quantum systems. As a proof-of-concept, we demonstrate near perfect Hong-Ou-Mandel interference between photons generated by a barium ion and a rubidium Rydberg ensemble. To spectrally match the ion photon's optical frequency to the that of the neutral atom system, we use quantum frequency conversion to convert the barium ion's photon to a wavelength matching the ensemble-produced photon. Our work forms the building blocks of a photonically linked hybrid ion-Rydberg ensemble quantum network.
