Nitrogen Plasma Passivated Niobium Resonators for Superconducting Quantum Circuits
K. Zheng, D. Kowsari, N. J. Thobaben +6
Microwave loss in niobium metallic structures used for superconducting quantum circuits is limited by a native surface oxide layer formed over a timescale of minutes when exposed t…

Optical Direct Write of Dolan--Niemeyer-Bridge Junctions for Transmon Qubits
J. T. Monroe, D. Kowsari, K. Zheng +4
We characterize highly coherent transmon qubits fabricated with a direct-write photolithography system. Multi-layer evaporation and oxidation allows us to change the critical curre…
