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…
Vortex Motion Induced Losses in Tantalum Resonators
Faranak Bahrami, Matthew P. Bland, Nana Shumiya +17
Tantalum (Ta) based superconducting circuits have been demonstrated to enable record qubit coherence times and quality factors, motivating a careful study of the microscopic origin…
Revealing the Origin and Nature of the Buried Metal-Substrate Interface Layer in Ta/Sapphire Superconducting Films
Aswin kumar Anbalagan, Rebecca Cummings, Chenyu Zhou +14
Despite constituting a smaller fraction of the qubits electromagnetic mode, surfaces and interfaces can exert significant influence as sources of high-loss tangents, which brings f…
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…
