Investigation of coherence of niobium-based resonators enabled by a fast-sealing microwave cavity
Chi Zhang, Richard Germond, Noah Janzen +3
Resonators and qubits with a niobium (Nb) base metal layer achieve some of the highest coherence times in superconducting quantum devices. The performance of such devices is often…

Tunable Coupler for Mediating Interactions between a Two-Level System and a Waveguide from a Decoupled State to the Ultra-Strong Coupling Regime
N. Janzen, X. Dai, S. Ren +2
Two-level systems (TLS) coupled to waveguides are a fundamental paradigm for light-matter interactions and quantum networks. We introduce and experimentally demonstrate a method to…

Aluminum air bridges for superconducting quantum devices realized using a single step electron-beam lithography process
Noah Janzen, Michal Kononenko, Shaun Ren +1
In superconducting quantum devices, air bridges enable increased circuit complexity and density as well as mitigate the risk of microwave loss arising from mode mixing. We implemen…
