Achieving Hong-Ou-Mandel Interference Between a trapped ion and Rydberg ensemble

POSTER

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 [1] 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. [1] J D. Siverns, J. Hannegan, and Q. Quraishi, Phys. Rev. Applied 11, 014044 (2019).
