Substrate insulated Josephson junctions for superconducting quantum circuits
U. Strobel, L. Radtke, L. Kamps +7
We have developed a fabrication technique for Josephson junctions that employs a three-dimensional patterned, low-loss substrate instead of commonly used organic resists. The techn…
Sideband Spectroscopy in the Strong Driving Regime: Volcano Transparency and Sideband Anomaly
Luka Antonic, Sergey Hazanov, Sergei Masis +2
We study the response of a spin to two crossed magnetic fields: a strong and fast transverse field, and a weak and slow longitudinal field. We characterize the sideband response at…
Material Loss Model Calibration for Tantalum Superconducting Resonators
Guy Moshel, Sergei Masis, Moshe Schechter +1
Material research is a key frontier in advancing superconducting qubit and circuit performance. In this work, we develop a simple and broadly applicable framework for accurately ch…
Resonant escape in Josephson tunnel junctions under millimeter-wave irradiation
J. N. Kämmerer, S. Masis, K. Hambardzumyan +5
The microwave-driven dynamics of the superconducting phase difference across a Josephson junction is now widely employed in superconducting qubits and quantum circuits. With the ty…
