Simone Frasca, C. Roy, Guillaume Beaulieu, Pasquale Scarlino · Physical Review Applied · 2024
Parametric amplifiers are essential in modern quantum technology, for enhancing weak signals with the minimal added noise of half a photon, and for working at higher temperatures and magnetic fields than Josephson junctions can handle. The authors present a kinetic inductance parametric amplifier (KIPA) that excels in dynamic range, operational temperature, and magnetic field resilience, and offers quantum-limited amplification. This KIPA's robust performance and compatibility promise transformative impacts on quantum information processing and low-temperature quantum research.
