Review of germanium-silicon single-photon avalanche diodes
Neil Na, Erik Chen, Gerald S. Bullerb +2
While it took about a decade for a germanium (Ge) thin film grown on a silicon (Si) substrate to be successfully applied as a detector material for high-speed optical fiber communi…
Reaching the intrinsic performance limits of superconducting nanowire single-photon detectors up to 0.1 mm wide
Kristen M. Parzuchowski, Eli Mueller, Bakhrom G. Oripov +13
Superconducting nanowire single-photon detectors (SNSPDs) combine high detection efficiency, low noise, and excellent timing resolution, making them a leading platform for photon-c…
Quasiparticle Dynamics in NbN Superconducting Microwave Resonators at Single Photon Regime
Paniz Foshat, Shima Poorgholam-khanjari, Valentino Seferai +7
Exchanging energy below the superconducting gap introduces quasiparticle energy distributions in superconducting quantum circuits, which will be responsible for their decoherence.…
Engineering high-Q superconducting tantalum microwave coplanar waveguide resonators for compact coherent quantum circuits
Shima Poorgholam-Khanjari, Valentino Seferai, Paniz Foshat +5
Tantalum (Ta) has recently received considerable attention in manufacturing robust superconducting quantum circuits. Ta offers low microwave loss, high kinetic inductance compared…
