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…
Tantalum Damascene Coplanar Waveguide Resonators Fabricated Using 300 mm Scale Processes
Ekta Bhatia, Yingge Du, Krishna P Koirala +12
Surface oxides contribute to losses in superconducting transmon devices resulting in degraded performance. We explore the use of the damascene process to replace the sidewall nativ…
3(111) Grain Boundaries Accelerate Hydrogen Insertion into Palladium Nanostructures
K. A. U. Madhushani, H. Park, H. Zhou +5
Grain boundaries (GBs) are frequently implicated as key defect structures facilitating metal hydride formation, yet their specific role remains poorly understood due to their struc…
Symmetry-mediated quantum coherence of spins in an oxygen-deficient double perovskite
Shannon Bernier, Mekhola Sinha, Tyler J. Pearson +7
Elucidating the factors limiting quantum coherence in real materials is essential to the development of quantum technologies. Here we report a strategic approach to determine the e…
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…
Hole-induced insulator-to-metal transition in La1-xSrxCrO3 epitaxial films
K. H. L Zhang, Y. Du, P. V. Sushko +5
We have investigated the evolution of the electronic properties of La1-xSrxCrO3 (for the full range of x) epitaxial films deposited by molecular beam epitaxy (MBE) using x-ray diff…
