Demonstrating Single Photon Counting with Kinetic Inductance Detectors from 3.8 to 25 m
Wilbert G. Ras-Vinke, Kevin Kouwenhoven, Jochem J. A. Baselmans +4
One of the primary objectives of modern astronomy is the atmospheric characterization of Earth-like exoplanets at visible and infrared wavelengths. Achieving this goal requires ext…
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…
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…
Geometry dependence of TLS noise and loss in a-SiC:H parallel plate capacitors for superconducting microwave resonators
K. Kouwenhoven, G. P. J. van Doorn, B. T. Buijtendorp +6
Parallel plate capacitors (PPC) significantly reduce the size of superconducting microwave resonators, reducing the pixel pitch for arrays of single photon energy-resolving kinetic…
