New publication: “Single-photon imager based on a superconducting nanowire delay line”
We demonstrate a scalable single-photon imager using a single continuous superconducting nanowire that is not only a single-photon detector but also functions as an efficient microwave delay line. In this... Read more >>

New Paper: “Free space-coupled superconducting nanowire single photon detectors for infrared optical communications”
This paper describes the construction of a cryostat and an optical system with a free-space coupling efficiency of 56.5% +/- 3.4% to a superconducting nanowire single-photon detector (SNSPD) for infrared quantum communication... Read more >>

New paper: “Eight-fold signal amplification of a superconducting nanowire single-photon detector using a multiple-avalanche architecture” accepted to Optics Express
[pdf] [abstract] Superconducting nanowire avalanche single-photon detectors (SNAPs) with n parallel nanowires are advantageous over single-nanowire detectors because their output signal amplitude scales linearly with n. However, the SNAP architecture has not been viably demonstrated... Read more >>
