WELL THERMALIZED MICROSTRIP FORMATION FOR FLEXIBLE CRYOGENIC MICROWAVE LINES IN QUANTUM APPLICATIONS

摘要

A microstrip that is usable in a quantum application (q-microstrip) includes a ground plane, a polyimide film disposed over the ground plane at a first surface of the polyimide film, and a conductor formed on a second side of the polyimide film such that the first surface is substantially opposite to the second surface. A material of the conductor provides greater than a threshold thermal conductivity (TH) with a structure of a dilution fridge stage (stage).
