Characterization of CPW resonators on InAs-Al heterostructures

ORAL

Abstract

Superconducting microwave coplanar waveguide (CPW) resonators are essential for many quantum devices. From applications in quantum information to sensing CPW resonators are used as an integral part of superconducting circuits. In the pursuit of InAs-Al based microwave devices we characterize resonators with relevant substrates: InP, InAlAs, and the full hybrid structure. We have studied the internal and external Q factors from the complex transmission signal. Furthermore, we also investigate the influence of environmental terms to find the limitations for microwave circuits on this III-V platform.
