Multilayer Microwave Integrated Quantum Circuits: Part 2

Superconducting quantum circuits provide a promising platform for quantum information processing. Resonant modes found in superconducting enclosures can be engineered to offer superior coherence and a better electromagnetic environment than their planar analogues. Here, we will discuss the Multilayer Microwave Integrated Quantum Circuit (MMIQC). A crucial component of the MMIQC is the realization of a high quality superconducting enclosure. The ability to make such a component necessitates the production of a high quality superconducting seam. In this talk, we will present an indium bump-bonding approach to produce superconducting seams with RF conductance exceeding 10^10/Ωm.
