超导的 nanowire 的研究单个光子的察觉者(SNSPD ) 在最近的年里很快一直在进行。SNSPD 的高效率,低噪音,和快速度的联合性质允许它从长途的量远距传物到 moon-to-earth 的应用光通讯。这里,我们简短讨论了 SNSPD 的最近的进步,特别地(1 ) tungsten-silicide SNSPD,(2 ) 波导综合的 SNSPD,并且(3 ) 一些应用示范。
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.
