Quantum fluctuations or equilibrium thermal fluctuations cannot explain the single photons and small light pulses coming out of the scintillator detector in between interactions with external particles or residual radioactivity events. The processes of energy accumulation and delayed release may explain these effects. Similar arguments can be built for other detectors, including solid-state...
Hafnium (Hf) is a superconducting material that has been gaining popularity among the superconducting detector community – for e.g. TES bolometers (Rotermund et al. in prep), TES calorimeters (Lita et al. 2009, Safonova et al. 2024), optical and near-IR MKIDs (Zobrist et al. 2019, Coiffard et al. 2020), phonon-sensitive MKIDs (Li et al. in prep), STJ (STAR Cryoelectronics SBIR awarded 2022),...
Particle-induced crystalline defects are critical in various applications, from detecting dark matter and Coherent Elastic Neutrino-Nucleus Scattering (CE$\nu$NS) to enhancing quantum computing devices. Defects within crystals can store energy, which directly influences particle interaction spectra and detection sensitivity. Furthermore, pre-existing defects can anneal over time, potentially...
We present the development of a kinetic-inductance traveling-wave parametric amplifier (KI-TWPA) based on NbTiN and TiN microstrip transmission lines optimized for sub-GHz and GHz frequency ranges. KI-TWPAs exploit nonlinear mixing processes enabled by the kinetic inductance of superconducting transmission lines, delivering wide instantaneous bandwidth, near quantum-limited noise performance,...
Parametric amplifiers continue to be vital components in solid state quantum readout at cryogenic temperatures. Various flavors of parametric amplifiers are carving their place in a number of different readout architectures. Josephson junction (JJ) based amplifiers are the natural progression when these readout architectures are at deep cryogenic temperatures. Josephson traveling wave...
