*Work at LANL was carried out under the auspices of the US DOE NNSA under Contract No. 89233218CNA000001 through the LDRD Program, and was performed, in part, at the Center for Integrated Nanotechnologies, an Office of Science User Facility operated for the U.S. DOE Office of Science, under user proposals #2018BU0010 and #2018BU0083. Work at UW was supported by the Center on Programmable Quantum Materials, an Energy Frontier Research Center funded by DOE BES under award DE- SC0019443.
