Multiphysics Numerical Method for Modeling Josephson Traveling-Wave Parametric Amplifiers
Samuel T. Elkin, Michael Haider, Thomas E. Roth
Josephson traveling-wave parametric amplifiers (JTWPAs) are wideband, ultralow-noise amplifiers used to enable the readout of superconducting qubits. While individual JTWPAs have a…
