Quantum Optics Group
The group research area is centered on the quantum properties of light that is produced by many different optical systems. It consists of experimental and theoretical studies concerning quantum fluctuations of light, generation of entangled states, interaction between quantum light and matter, nanophotonics, and quantum metrology.

Stage de Master 2 – Trous noirs artificiels dans les fluides quantiques de lumière.
Fluides quantiques de lumière Les photons sont d'excellents porteurs d'information, mais ils n'interagissent généralement pas entre eux. Les atomes interagissent, mais ils sont difficiles à manipuler et ne bénéficient pas de l'arsenal de l'optique quantique pour...

Postdoctoral Fellowship (2 to 4 years) on Quantum Fluids of light at LKB, Paris
We are looking for an highly motivated postdoc to work on a novel experiment with quantum fluids of light: the creation of synthetic photonic matter by engineering a quantum phase transition for light. Photons are great carriers of information but they usually don’t...
Post-doc position: Optical Quantum parameter estimation: from theory to experiments
Overview A fundamental task in quantum metrology is to identify the ultimate sensitivity limit in the estimation of a parameter encoded into a quantum state. Even under ideal conditions, when all technical noise sources are removed, quantum noise poses unavoidable...

Post-doc position: Large-scale non-Gaussian entanglement and applications
Scientific context Our group, the multimode quantum optics group of Laboratoire Kastler Brossel, pioneered many aspects of continuous variable (CV) approach to quantum optics. Our main objects of interest are the quadratures of the electric field, which are typically...
Hybride-nanophotonic devices for quantum technology applications
Quantum communication experiments developed for communication networks require single photon sources with a tunable frequency and a narrow linewidth. Semiconductor quantum dots are good candidates for realizing such sources, but they need to be coupled to high finesse...
Stage : Quantum simulation of black hole effects with fluids of light
Analogue gravity is a type of analogue quantum simulation that enables the study of gravitational effects in the laboratory [1]: it is possible to create conditions in which waves in media propagate as though they were in the vicinity of a black hole [2] or on an...
PostDoc Position: Analogue Gravity in polariton superfluids
Analogue gravity enables the study of fields on curved spacetimes in the laboratory [1]: it is possible to create conditions in which waves in media propagate as though they were in the vicinity of a black hole [2] or on an expanding universe [3], for example. In the...
Open post-doc position – Quantum frequency combs for multimode non-Gaussian states with application to quantum metrology
Overview Our group, the multimode quantum optics group of Laboratoire Kastler Brossel, pioneered many aspects of continuous variable (CV) approach to quantum optics. Our main objects of interest are therefore the quadratures of the electric field, which are typically...
