Sébastien joined our group in December 2015 to September 2018. His research focused on the coupling of Rydberg atoms and superconducting qubits in microwave cavities. He previously worked on the development of fiber interfaces between single atoms and single optical photons during his PhD at Laboratoire Kastler Brossel, Ecole Normale Supérieure, in Paris, France. After leaving QuDev, Sébastien moved on to "Equipe Photonique Quantique at Collège de France".
