High Kinetic Inductance Superconducting Nanowire Resonators for Circuit QED in a Magnetic Field
N. Samkharadze, A. Bruno, P. Scarlino +4
We present superconducting microwave-frequency resonators based on NbTiN nanowires. The small cross section of the nanowires minimizes vortex generation, making the resonators resi…
Broadband architecture for galvanically accessible superconducting microwave resonators
Sal J. Bosman, Vibhor Singh, Alessandro Bruno +1
In many hybrid quantum systems, a superconducting circuit is required that combines DC-control with a coplanar waveguide (CPW) microwave resonator. The strategy thus far for applyi…
Realization of microwave quantum circuits using hybrid superconducting-semiconducting nanowire Josephson elements
G. de Lange, B. van Heck, A. Bruno +6
We report the realization of quantum microwave circuits using hybrid superconductor-semiconductor Josephson elements comprised of InAs nanowires contacted by NbTiN. Capacitively-sh…
Reducing intrinsic loss in superconducting resonators by surface treatment and deep etching of silicon substrates
A. Bruno, G. de Lange, S. Asaad +3
We present microwave-frequency NbTiN resonators on silicon, systematically achieving internal quality factors above 1 M in the quantum regime. We use two techniques to reduce losse…
