Wireless communication based on microwave photon-level detection with superconducting devices: Achievable rate prediction

Future wireless communication system embraces physical-layer signal detection with high sensitivity, especially in the microwave photon level. Currently, receiver primarily adopts based on semi-conductor devices for detection, while this paper introduces high-sensitivity photon-level superconducting structure. We first overview existing works optical spectrum as well sensing structure both theoretical and experimental perspectives, including circuit model Josephson junction, counter two reconstruction approaches under background noise. In addition, we characterize channel modeling different approaches, absorption barrier dual-path Handury Brown-Twiss (HBT) experiments, predict corresponding achievable rates. According to performance prediction, it is seen that can increase sensitivity compared state-of-the-art standardized waveform reception, gain over 10dB.
