Abstract

As superconducting quantum circuits grow in size and complexity, a number of unwanted effects arise which limit architecture scalability. Multilayer quantum circuits have the potential to solve many of these issues. In this seminar, we will examine an addition to the multilayer quantum circuit toolbox: the technique of indium thin film thermocompression bonding. We will characterize this technique as applied to tunnel-capped superconducting quantum devices. We will also explore the characterization of aluminium/indium and indium thin films using the two level system loss model.
