Superconducting nanowire single-photon detectors: recent progress


Research of superconducting nanowire single-photon detectors (SNSPDs) has been progressing rapidly in recent years. The combined properties of high efficiency, low noise, and fast speed of SNSPDs permit its applications ranging from long-distance quantum teleportation to moon-to-earth optical communications. Here we briefly discussed recent progress of SNSPDs, in particular (1) tungsten-silicide SNSPDs, (2) waveguide-integrated SNSPDs, and (3) a few applied demonstrations.


超导纳米线单光子探测器这一研究领域进展迅速。此种探测器同时具有效率高、噪声低、速度快的特性, 在长距离量子隐态传输、月地光通信方面皆有应用。我们简短评述超导纳米线单光子探测器的最新进, 尤其是 (1)硅化钨超导纳米线单光子探测器、(2)波导集成的超导纳米线单光子探测器、(3)一些应用展示。
