Our final goal from this project is to realize on-demand single- and multi-photon sources that are key resources for quantum communication and computation technology we have made significant progress toward that goal under this DURIP grant. In order to efficiently overcome the probabilistic generation of heralded photons via spontaneous parametric down-conversion SPDC, and to realize an on-demand single-photon source, one can employ time-multiplexing. In this project, we have extended and implemented a time-multiplexed heralded single-photon source with a low-loss and high-speed optical storage system. We have observed that our preliminary implementation with our current existing SPDC source outperforms all previous demonstrations of heralded single-photon sources. Moreover, we have made substantial progress in our efforts to optimize a SPDC photon-pair source for time multiplexing, accounting theoretical and practical aspects.
