Research Interests

My main research interests lie in revealing different types of non-classical signatures of quantum states in quantum phase-space and designing practical implementations in optical interferometry in order to detect these non-classicalities. I also used theoretical tools from quantum parameter estimation to design an optimal communication protocol to send classical parameters encoded in quantum coherent states.

Besides my research activities as a PhD student at QuIC under the supervision of Nicolas J. Cerf, I am also employed by the Solvay Brussels Schoof of Economics and Management as a teaching assistant in Physics and Technologies. I teach the practical exercises sessions and labs in the General Physics and Physics for Information Technologies courses and I supervise a seminar on new technologies.
