The University of Illinois Urbana-Champaign team has won an award for a two-year program from the Air Force Office of Scientific Research to look at ways of reducing defects in the deposition process of the aluminum/aluminum oxide/aluminum junctions used in superconducting Josephson junctions. Defects in the junction can negatively impact coherence time in a superconducting qubit so improvements that can reduce the disorder in the material can help improve the overall qubit quality. The team will be using transmission electron microscopy (TEM) as well as low temperature characterization to be able to develop a full picture of a the Josephson junction deposition. Additional information is available in a news release posted by the University of Illinois here.
