Abstract
Photon counting applications are often limited by detector deadtime to operate at count rates of a few MHz, at best, and often at significantly lower levels. This limitation is becoming more critical as with the advance of photon counting applications such as photon-based quantum information. We present a first experimental proof of principle and review the theoretical foundation of a multiplexed detection scheme that allows photons to be counted at much higher rates than is possible with individual detectors or simple detector trees. In addition to the deadtime improvement, we discuss the impact of this scheme on other important characteristics such as afterpulsing and dark count rates.Citation
