  1. 1. Cold amplification and fiber coupling of a super-conducting nanowire single-photon detector

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Stéphane Cohen; [2022]
    Nyckelord :Applied Physics; Tilllämpad fysik;

    Sammanfattning : Single-photon detectors are an essential tool for quantum photonics: one can harness the quantum properties of single photons for quantum communication as well as use the detectors in low illumination applications.Superconducting nanowire single-photon detectors offer high detection efficiency over a widerange of wavelengths, low dark counts, and a good timing resolution compared to single-photonavalanche diodes.
