The Quantum Engineering group gathers the groups of cold atoms and matter wave interferometry. It has been created in September 2015.


We are working on a number of experimental and theoretical projects. The cold atoms team explores the possibilities offered by BEC machine to realize quantum simulations, chaos or atom optics.The atom interferometry team develop quantum sensors based on matter waves intererences with applications in applied science and in fundamental physics. 

The theory part is developed alongside the experimental activities and also about some quantum engineering topics such as shortcuts to adiabaticity.
