# 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.

## 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...

## Open PhD position – quantum complex communication networks

ERC consolidator grant COQCOoN ( PI: Valentina Parigi - valentina.parigi@lkb.upmc.fr) Complex network theory has provided a deep insight of complex systems, assembling theoretical tools able to the describe dynamical behavior of biological, social and technological...

## Internship: steering non-Gaussian quantum states

The multimode quantum optics group has an open position for a theory internship to study the connection between quantum steering and non-Gaussian effects.

## Optomechanical signature of superfluidity of light – Open PhD position

Optomechanical signature of superfluidity of light - Open PhD position Most work in many body-physics (theoretical and experimental) are dealing with massive material particules (atoms, electrons...). However, we know since the early days of quantum mechanics that...
