Ultrafast Laser System for Producing on-Demand Single-and Multi-Photon Quantum States

Abstract

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.
