Transforming Native Oxide into a Metallic Platinum--Niobium Alloy for Passivation of Superconducting Niobium Films
Ananya Chattaraj, Conan Weiland, Bruce Ravel +10
Dielectric losses at surfaces and interfaces remains a primary limitation to coherence in superconducting transmon qubits. Niobium (Nb), a widely used material in superconducting q…
Polymer-Iron Oxide Hybrid Films for Controlling Electrokinetic Properties
Austin Dick, Xiao Tong, Kim Kisslinger +2
Electrokinetic phenomena at polymer-water interfaces are central to technologies for water purification, ion separations, and energy conversion, yet the ability to systematically c…
Evolution of the Fermi surface of 1T-VSe across a structural phase transition
Turgut Yilmaz, Xiao Tong, Jerzy T. Sadowski +4
The electronic origin of the structural transition in 1T-VSe is re-evaluated through an extensive angle-resolved photoemission spectroscopy experiment. The components of the ba…
Ultrathin Magnesium-based Coating as an Efficient Oxygen Barrier for Superconducting Circuit Materials
Chenyu Zhou, Junsik Mun, Juntao Yao +15
Scaling up superconducting quantum circuits based on transmon qubits necessitates substantial enhancements in qubit coherence time. Among the materials considered for transmon qubi…
