Effect of the wire width on the intrinsic detection efficiency of superconducting-nanowire single-photon detectors
R. Lusche, A. Semenov, H. -W. Huebers +7
Thorough spectral study of the intrinsic single-photon detection efficiency in superconducting TaN and NbN nanowires with different widths shows that the experimental cut-off in th…
Temperature-dependence of detection efficiency in NbN and TaN SNSPD
Andreas Engel, Kevin Inderbitzin, Andreas Schilling +7
We present systematic measurements of the temperature-dependence of detection efficiencies in TaN and NbN superconducting nanowire single-photon detectors. We have observed a clear…
Break-up of long-range coherence due to phase fluctuations in ultrathin superconducting NbN films
Y. Noat, T. Cren, C. Brun +7
Using scanning tunneling spectroscopy (STS), we address the problem of the superconductor-insulator phase transition (SIT) in homogeneously disordered ultrathin (2-15 nm) films of…
Current Assisted, Thermally Activated Flux Liberation in Ultrathin Nanopatterned NbN Superconducting Meander Structures
H. Bartolf, A. Engel, A. Schilling +4
We present results from an extensive study of fluctuation phenomena in superconducting nanowires made from sputtered NbN. Nanoscale wires were fabricated in form of a meander and o…
Losses in coplanar waveguide resonators at millikelvin temperatures
P. Macha, S. H. W. van der Ploeg, G. Oelsner +4
We study the loss rate for a set of lambda/2 coplanar waveguide resonators at millikelvin temperatures (20 mK - 900mK) and different applied powers (3E-19 W - 1E-12 W). The loss ra…
Weak continuous monitoring of a flux qubit using coplanar waveguide resonator
G. Oelsner, S. H. W. van der Ploeg, P. Macha +9
We study a flux qubit in a coplanar waveguide resonator by measuring transmission through the system. In our system with the flux qubit decoupled galvanically from the resonator, t…
