Progress towards a broadband traveling wave Josephson parametric amplifier
Abstract
Most Josephson parametric amplifiers are based on a resonant circuit architecture with associated bandwidth limitations. We examine the use of a `Josephson nonlinear fiber' -- a transmission line periodically loaded with Josephson junctions -- as an inherently broadband traveling wave parametric amplifier. We report on the device design, calculations of gain and bandwidth from a simple model, and preliminary measurement results. We acknowledge the ONR and the Hertz Foundation for financial support.
