Tuning of flux tunable superconducting resonators

Our lab’s first flux-tunable superconducting resonators are now on arXiv. We show how one can efficiently modulate these FTRs using chip-based modulation techniques. This work is part of our group’s efforts to generate macroscopic quantum states of levitated superconducting microparticles.

Thanks to the efforts from our group by Achintya Paradkar (main actor!), Paul Nicaise, Karim Dakroury and Fabian Resare, and by our co-workers from the EU project SuperMeQ Christian Dejaco, Lukas Deeg and Gerhard Kirchmair.

I want to also thank Amr Osman, Anita Fadavi and Jonas Bylander for the strong support in microfabrication we have received at the Quantum Technology lab at Chalmers Department of Microtechnology and Nanoscience at Chalmers University of Technology.
