Abstract
The single photon detectors currently used in quantum communication schemes impose considerable restrictions on signal registration and dark count rates, require cooling to low temperatures, and are relatively expensive. Alternative approaches have recently been proposed that are based on the homogeneous and heterogeneous detection of quantum signals and can be used with conventional photodetectors. This work studies the possibility of obtaining a heterogeneous detection scheme in a subcarrier wave quantum communication system that could be used to create quantum networks.
