I am a permanent CNRS researcher at the Néel Institute since 2020. I am part of the superconducting quantum circuits group.
My research generally aims to investigate light-matter interactions in circuits and nanostructures. We conceive experiments to explore the fundamental physics of phonons, spins and photons and we apply our findings to engineer novel quantum devices. These experiments take place on chips fabricated in house and operated at very low temperature (few mK) and microwave frequency (few GHz).
We currently focus on the development of acoustic devices in the quantum regime, with aims such as:
- to realize highly efficient interconnections between acoustic networks and superconducting microwave networks (perspectives: microwave-to-optics transduction, preparation of quantum states based on the non-linearity of Josephson junctions, acoustic spectroscopy)
- to study spin-phonon interactions (perspectives: efficient quantum control and readout of spin qubits)
