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.

We welcome Aditi to our lab, who joins the maglev team as a PhD student. She will research on the read-out and control of levitated superconducting microparticles based on superconducting circuit technology. This will be much fun!

Interested in a Master thesis project in our lab? The new projects are out now. We offer thesis projects for 30cr (half a year) and 60cr (full year) on the following topics:

• Two-dimensional photonic crystals for quantum cavity optomechanics
• Squashing the motion of a crystalline piezoelectric nanomechanical resonators
• Characterization and flux-locking of superconducting flux-tunable resonators
• Design, simulation and fabrication of superconducting flux-tunable resonators
• Developing metamaterial-based vibration shields for chip-based magnetic traps
• Flexible microwave cables for cryogenic quantum experiments

Interested? Just get in contact with us!

You can also find these projects on Chalmers thesis portal.

How can one reduce adhesion of a microparticle resting on a silicon substrate? Interested? Some ideas are explored in our recent work: https://arxiv.org/abs/2508.13887

Thanks to the fantastic work by Fabian and Somiya!

We welcome Thomas Penny to our lab! Tom joins our maglev team as a PostDoc. He brings in his expertise from optical levitation experiments performed in David Moore’s group at Yale and Peter Barker’s group at UCL.
