Single-photon counting techniques using single-photon detectors (SPDs) are needed in a variety of emerging quantum measurement and communication applications. To meet these needs, the development of ultrasensitive, high precision quantum sensing and measurement devices (i.e. not obtainable with classical methods) will play a key role in future NASA, commercial and other government communication and analysis systems. Nanohmics, Inc. and Prof. Anton Malkorsquo;s research group at the University of Texas at Dallasnbsp;is to develop a laser-pump on-demand single-photon pair source based on biexciton cascade emission in semiconductor quantum dots for correlated calibration of SPDs. Relative to the approach of spontaneous parametric down-conversion in generating single-photon pairs, the proposed technology has advantages of on-demand photon pair generation, high efficiency, low-cost, and scalability. During Phase I, we demonstrated high biexciton cascade emission efficiency in single colloidal QDs nanocrystals and fabricated bullseye antenna to enhance photon emission of single QDs. During Phase II, we will integrate commercially availablenbsp;off-the-shelfnbsp;optics and electronics and incorporate QD-bullseye hybrid structures to construct a prototype optical system to generate single-photon pairs and demonstrate correlated calibration of SPDs.
