Recombination of localized quasiparticles in disordered superconductors
Steven A. H. de Rooij, Remko Fermin, Kevin Kouwenhoven +6
Disordered superconductors offer new impedance regimes for quantum circuits, enable a pathway to protected qubits, and can improve superconducting detectors due to their high kinet…
Commissioning the CMB polarization telescope GroundBIRD with the full set of detectors
Miku Tsujii, Jochem J. A. Baselmans, Jihoon Choi +39
GroundBIRD is a ground-based cosmic microwave background (CMB) experiment for observing the polarization pattern imprinted on large angular scales ( ) from the Teide Obse…
A 25-micron single photon sensitive kinetic inductance detector
Peter K. Day, Nicholas F. Cothard, Christopher Albert +15
We report measurements characterizing the performance of a kinetic inductance detector array designed for a wavelength of 25 microns and very low optical background level suitable…
Vibrational modes as the origin of dielectric loss at 0.27$\unicode{x2013}$100 THz in a-SiC:H
B. T. Buijtendorp, A. Endo, W. Jellema +9
Low-loss deposited dielectrics are beneficial for the advancement of superconducting integrated circuits for astronomy. In the microwave band (1$\unicode{x2013}$10 G…
Directional Filter Design and Simulation for Superconducting On-chip Filter-banks
Louis H. Marting, Kenichi Karatsu, Akira Endo +2
Many superconducting on-chip filter-banks suffer from poor coupling to the detectors behind each filter. This is a problem intrinsic to the commonly used half wavelength filter, wh…
Optimisation-based alignment of wideband integrated superconducting spectrometers for sub-mm astronomy
A. Moerman, K. Karatsu, S. J. C. Yates +7
Integrated superconducting spectrometers (ISSs) for wideband sub-mm astronomy utilise quasi-optical systems for coupling radiation from the telescope to the instrument. Misalignmen…
