Low-Frequency Noise Performance of Microstrip-Coupled Lumped-Element Aluminum KIDs using Hydrogenated Amorphous Silicon Parallel-Plate Capacitors for NEW-MUSIC
Simon Hempel-Costello, Andrew D. Beyer, Dan Cunnane +11
We present measurements of the low-frequency noise of microstrip-coupled, lumped-element aluminum kinetic inductance detectors that use hydrogenated amorphous silicon parallel-plat…
Quantum Parity Detectors: a qubit based particle detection scheme with meV thresholds for rare-event searches
Karthik Ramanathan, Brandon J. Sandoval, John E. Parker +5
The next generation of rare-event searches, such as those aimed at determining the nature of particle dark matter or in measuring fundamental neutrino properties, will benefit from…
Superconducting Parallel-Plate Resonators for the Detection of Single Electron Spins
André Pscherer, Jannes Liersch, Patrick Abgrall +7
We introduce a multilayer superconducting microwave resonator with sub-Ohm impedance optimized for high coupling strength to single electron spins. The design minimizes the magneti…
Improved Modeling of Quasi-Static Thermal and Optical Response of Lumped-Element Aluminum Manganese KIDs
Adriana Gavidia, Sunil Golwala, Andrew D. Beyer +11
We report on the optical characterization of the AlMn kinetic inductance detectors (KIDs) in development for use in the Next-generation Extended Wavelength-MUltiband Sub/millimeter…
Assessing the operating characteristics of an ion-milled phonon-mediated quantum parity detector
Brandon J. Sandoval, Andrew D. Beyer, Pierre M. Echternach +4
Phonon sensitive superconducting qubits promise to provide sub-eV energy deposit thresholds, useful for future rare-event experiments looking for interactions from dark matter and…
Low two-level-system noise in hydrogenated amorphous silicon
Fabien Defrance, Andrew D. Beyer, Jordan Wheeler +2
At sub-Kelvin temperatures, two-level systems (TLS) present in amorphous dielectrics source a permittivity noise, degrading the performance of a wide range of devices using superco…
