Characterization of NbTiN films with thicknesses below 20 nm for low power kinetic inductance amplifiers
A. Giachero, M. R. Vissers, J. D. Wheeler +6
A quantum-limited amplification chain is a fundamental advantage for any application that may benefit from the detection of very faint signals. Reading out arrays of superconductin…
Improved microwave SQUID multiplexer readout using a kinetic-inductance traveling-wave parametric amplifier
M. Malnou, J. A. B. Mates, M. R. Vissers +5
We report on the use of a kinetic-inductance traveling-wave parametric amplifier (KITWPA) as the first amplifier in the readout chain of a microwave superconducting quantum interfe…
G4CMP: Condensed Matter Physics Simulation Using the Geant4 Toolkit
M. H. Kelsey, R. Agnese, Y. F. Alam +44
G4CMP simulates phonon and charge transport in cryogenic semiconductor crystals using the Geant4 toolkit. The transport code is capable of simulating the propagation of acoustic ph…
CCAT-prime: Characterization of the First 280 GHz MKID Array for Prime-Cam
Steve K. Choi, Cody J. Duell, Jason Austermann +20
The Prime-Cam receiver on the Fred Young Submillimeter Telescope for the CCAT-prime project aims to address important astrophysical and cosmological questions with sensitive broadb…
Performance of a Kinetic-Inductance Traveling-Wave Parametric Amplifier at 4 Kelvin: Toward an Alternative to Semiconductor Amplifiers
M. Malnou, J. Aumentado, M. R. Vissers +4
Most microwave readout architectures in quantum computing or sensing rely on a semiconductor amplifier at 4 K, typically a high-electron mobility transistor (HEMT). Despite its rem…
Study of quasi-particle dynamics using the optical pulse response of asuperconducting resonator
J. Hu, Q. He, F. Yu +14
We study the optical pulse response of a superconducting half-wavelength coplanar waveguide (CPW) resonator. We apply a short optical pulse to the center strip of the CPW resonator…
Measurement of optical constants of TiN and TiN/Ti/TiN multilayer films for microwave kinetic inductance photon-number-resolving detectors
M. Dai, W. Guo, X. Liu +8
We deposit thin titanium-nitride (TiN) and TiN/Ti/TiN multilayer films on sapphire substrates and measure the reflectance and transmittance in the wavelength range from 400 nm to 2…
Cryogenic LED pixel-to-frequency mapper for kinetic inductance detector arrays
X. Liu, W. Guo, Y. Wang +8
We present a cryogenic wafer mapper based on light emitting diodes (LEDs) for spatial mapping of a large microwave kinetic inductance detector (MKID) array. In this scheme, an arra…
Optical Demonstration of THz, Dual-Polarization Sensitive Microwave Kinetic Inductance Detectors
B. Dober, J. A. Austermann, J. A. Beall +17
The next generation BLAST experiment (BLAST-TNG) is a suborbital balloon payload that seeks to map polarized dust emission in the 250 m, 350 m and 500 m wavebands. The ins…
Strongly quadrature-dependent noise in superconducting micro-resonators measured at the vacuum-noise limit
J. Gao, L. R. Vale, J. A. B. Mates +8
We measure frequency- and dissipation-quadrature noise in superconducting lithographed microwave resonators with sensitivity near the vacuum noise level using a Josephson parametri…
