With the rapid development of microwave photonics technology,high-speed processing and ultra-weak signal detection capability have become the main bottlenecks in many applications.Thanks to the ultra-weak signal detection capability and the extremely low timing jitter properties of single-photon detec-tors,the combination of single-photon detection and classical microwave photonics technology may pro-vide a solution to break the above bottlenecks.In this paper,we first report a novel concept of single-photon microwave photonics(SP-MWP),a SP-MWP signal processing system with phase shifting and fre-quency filtering functionalities is demonstrated based on a superconducting nanowire single photon detector(SNSPD)and a successive time-correlated single photon counting(TCSPC)module.Experimental results show that an ultrahigh optical sensitivity down to-100 dBm has been achieved,and the signal processing bandwidth is only limited by the timing jitter of single-photon detectors.In the meantime,the proposed system demonstrates an ultrahigh anti-interference capability,only the sig-nal which is phase locked by the trigger signal in TCSPC can be extracted from the detected signals com-bining with noise and strong interference.The proposed SP-MWP concept paves a way to a novel interdisciplinary field of microwave photonics and quantum mechanism,named by quantum microwave photonics.
