AMKID -- a large KID-based camera at the APEX telescope
N. Reyes, A. Weiss, S. J. C. Yates +26
The thermal emission at sub-millimeter wavelengths carries unique information in many astronomical applications ranging from disks and planet formation around young stars, to galax…
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…
DESHIMA 2.0: A 200-400 GHz Ultra-wideband Integrated Superconducting Spectrometer
K. Karatsu, A. Endo, A. Moerman +26
DESHIMA (Deep Spectroscopic HIgh-redshift MApper) is a broadband integrated superconducting spectrometer (ISS) for millimeter (mm) / sub-millimeter (sub-mm) wave astronomy based on…
Demonstration of Ultra-Sensitive KIDs for Future THz Space Borne Polarimeters
Stephen J. C. Yates, Alejandro Pascual Laguna, Willem Jellema +8
We present measurements and simulations of the polarization purity of leaky lens-antenna coupled microwave Kinetic Inductance Detectors (KIDs) at 1.5 THz. We find the integrated cr…
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…
Volume dependence of microwave induced excess quasiparticles in superconducting resonators
Steven A. H. de Rooij, Jochem J. A. Baselmans, Juan Bueno +3
The presence of quasiparticles typically degrades the performance of superconducting microwave circuits. The readout signal can generate non-equilibrium quasiparticles, which lead…
