Performance of a SuperCDMS HVeV Detector with Sub-eV Energy Resolution and Single Charge-sensitivity
Kyle Kennard, Aditi Pradeep, Mason Buchanan +41
We present a detailed characterization of a new generation of athermal-phonon single-charge sensitive Si HVeV detectors, the best of which achieved 589~meV~~5~meV baseline res…
Correcting impedance measurements for background parasitics to characterize circuit components in cryogenic environments
Riley J. Carpenter, Jadyn Anczarski, Ivar Rydstrom +4
Predictable circuit response is a critical prerequisite for accurate electronic measurements. We describe a powerful, yet straightforward, experimental method and analysis model th…
The Superconducting Quasiparticle-Amplifying Transmon: A Qubit-Based Sensor for meV Scale Phonons and Single THz Photons
Caleb W. Fink, Chiara P. Salemi, Betty A. Young +2
With great interest from the quantum computing community, an immense amount of R&D effort has been invested into improving superconducting qubits. The technologies developed for th…
Cryogenic optical beam steering for superconducting device calibration
K. Stifter, H. Magoon, A. J. Anderson +22
We have developed a calibration system based on a micro-electromechanical systems (MEMS) mirror that is capable of delivering an optical beam over a wavelength range of 180 -- 2000…
