Surface Platinum Alloying for Passivation of Oxide Interfaces on Superconducting Niobium Films

Ananya Chattaraj, Conan Weiland, Bruce Ravel +10

Dielectric loss arising from two-level systems (TLS) at surfaces and interfaces remains a primary limitation to coherence in superconducting transmon qubits. Niobium (Nb), a widely…

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…
