Quantum computers hold potential to solve scientific and energy related problems intractable for classical hardware and algorithms. One promising avenue for quantum computers uses superconducting circuits to act as artificial atoms. Limiting such approaches are materials defects in the constituent circuit elements which consist of various superconductor, insulator, and interfacial layers. These defects break quantum coherence, which causes quantum computations to be lost before they can be read-out.
Our group is working on low defect density materials platforms for superconducting quantum circuits. Based on rocksalt nitrides, we have identified a unique suite of materials such that each element is inherently low-loss, chemically compatible, and structurally commensurate. We are working to understand the underlying materials defects that lead to decoherence as well as build epitaxial superconducting quantum circuits from them.
