Near-Quantum-Limited Readout for the Princeton Axion Search using a sub-GHz Kinetic Inductance Traveling Wave Parametric Amplifier

Joe Wiedemann, Roman Kolevatov, Jianyang Fu +7

Parametric amplifiers are a workhorse for near-quantum-limited measurements above 1 GHz. However, amplifier development has been more limited below 1 GHz. We present a kinetic indu…
