Abstract
A method of manufacturing a travelling wave parametric amplifier (TWPA) includes forming a superconducting junction on a substrate. Trenches are etched away through a metal surface and into a layer of dielectric material. The trenches define a plurality of fingers positioned in an interdigitated arrangement of capacitors defined by a metal and a dielectric material that remains from the etched away metal surface and the layer of dielectric material.
