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…
Low-Loss Superconducting Resonators Fabricated from Tantalum Films Grown at Room Temperature
Guillaume Marcaud, David Perello, Cliff Chen +16
The use of -tantalum in superconducting circuits has enabled a considerable improvement of the coherence time of transmon qubits. The standard approach to grow -tantalum thin…
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…
Atomic Insights into the Oxidative Degradation Mechanisms of Sulfide Solid Electrolytes
Chuntian Cao, Matthew R. Carbone, Cem Komurcuoglu +15
Electrochemical degradation of solid electrolytes is a major roadblock in the development of solid-state batteries, and the formed solid-solid interphase (SSI) plays a key role in…
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…
Diamond Surface Functionalization via Visible Light-Driven C-H Activation for Nanoscale Quantum Sensing
Lila V. H. Rodgers, Suong T. Nguyen, James H. Cox +16
Nitrogen-vacancy centers in diamond are a promising platform for nanoscale nuclear magnetic resonance sensing. Despite significant progress towards using NV centers to detect and l…
