Hanna Le Jeannic
CNRS Researcher at LKB Paris. Quantum and classical cats lover. Mycology enthusiast in her free (autumnal) time.
Short biography. After her engineering degree at ESPCI Paris, a French Grande École, she received her master degree in Optics, Matter and Plasmas at Institut d’Optique in 2013. She pursued her career in quantum optics with a PhD at Laboratoire Kastler Brossel, Sorbonne University (formerly Pierre and Marie Curie University), under the supervision of Pr. Julien Laurat, obtained in 2016. There she studied hybrid “continuous/discrete” quantum information processing: she worked on the generation of the first hybrid CV–DV entangled state using parametric down-conversion sources, on the implementation of a variety of hybrid protocols, and on non-Gaussian quantum state engineering.
Interested in the field of nanophotonics, she then spent three years as a postdoctoral researcher at the Niels Bohr Institute in Denmark, in the group of Pr. Peter Lodahl, working on quantum dots embedded in nanophotonic waveguides. In particular, she studied and used “giant” (i.e. single-photon-level) nonlinearities of light in this system, and unraveled part of the physics of the interaction of two photons with a single emitter.
She obtained a CNRS Researcher position (tenured, Associate Professor level) in December 2020, at the age of 30, and worked on quantum nanophotonics at Laboratoire Photonique, Numérique et Nanosciences (LP2N) until 2022, when she started her group at Laboratoire Kastler Brossel in the NanoOptics and Quantum Fluids of Light team. There she works on the coupling between photonic waveguides (in particular tapered optical nanofibers) and solid-state quantum emitters. She is a member of the scientific committee of the “Groupement de Recherche” on Quantum Technologies (IQFA).
