Traveling wave parametric amplifier with Josephson junctions using minimal resonator phase matching
Traveling wave parametric amplifier with Josephson junctions using minimal resonator phase matching
Josephson parametric amplifiers have become a critical tool in superconducting device physics due to their high gain and quantum-limited noise. Traveling wave parametric amplifiers (TWPAs) promise similar noise performance, while allowing for significant increases in both bandwidth and dynamic range. We present a TWPA device based on an LC-ladder transmission …
