Towards Improved End-to-End System Efficiency of Photon Pair systems



Alexander E. Ling, Alan L. Migdall, Jingyun Fan


We report on our efforts in integrating a source and detection system of photon pairs that have a high end-to-end system efficiency. This requires combining appropriate detectors and photon pair sources. Preliminary measurements show that an observed heralding efficiency of 65% for single photons is readily achieved.
