INMA Seminar: Fabien Defrance, from ICN2
Seminar: Superconductivity in Astrophysics and Quantum Technology
Speaker: Dr Fabien Defrance (ICN2, Barcelona). Dr Defrance has an extensive research background at the Paris Observatory, Caltech, and NASA’s Jet Propulsion Laboratory, specialising in superconducting detectors and metamaterial optics.
When and where?
- Date: Wednesday, 22 April 2026.
- Time: 12:00.
- Venue: Theoretical Physics Seminar Room (Atomic Physics corridor), Faculty of Sciences, University of Zaragoza.
Key topics:
- Astrophysical Technologies: A review of superconducting devices used in astrophysical receivers, with a focus on Kinetic Inductance Detectors (KIDs) due to their high sensitivity and frequency multiplexing capabilities.
- Noise Mitigation: Presentation of advancements in characterising and mitigating noise and loss in dielectrics at sub-Kelvin temperatures, which currently limit the performance of superconducting qubits.
- Quantum Transducers: Discussion on how superconducting resonators can be integrated with Yttrium Iron Garnet (YIG) microdisks to develop microwave-to-optical quantum transducers.
Organisers: This event is supported by INMA, CSIC, and the University of Zaragoza, under the Severo Ochoa Excellence accreditation.
