An international team has published a study in the journal Nature analyzing how the quantum phenomenon of superfluorescence appears in perovskite materials. The Irradiated Solids Laboratory (LSI*) is involved, thanks in particular to the work of Antonia Ghita, a former student of École polytechnique's Bachelor's program.
Created in January 2025 by Thales, world leader in high-power lasers, GenF aims to develop and industrialize a process for creating a new, safe, abundant, inexpensive and non-polluting form of energy using the inertial confinement nuclear fusion process. The inauguration of its premises in Le Barp, south of Bordeaux, was attended by representatives of the various stakeholders involved.
The year 2025 has been proclaimed International Year of Quantum Science and Technology by the United Nations. In the 20th century, quantum mechanics radically changed the way we think about the physical world. Today, quantum physics is in the midst of a renaissance that is opening up new and unexpected applications. Laurent Sanchez-Palencia, Director of Research at the Center for Theoretical Physics (CPHT*) and Deputy Director of the Quantum-Saclay center, gives us an overview of this “second quantum revolution”.
Operated by École polytechnique and CNRS, Apollon is one of the few facilities in the world with multiple laser beams whose power exceeds one petawatt (one million billion watts). Take a behind-the-scenes look at this infrastructure and the fundamental research being carried out there.
Winner of the 2018 Nobel Prize in Physics, Donna Strickland presented her current research work on ultrashort laser pulses and multi-frequency Raman generation processes.
The École polytechnique and the Fondation de l' École polytechnique are renewing the “Space: sciences and challenges of the space sector” teaching chair, with the support of ArianeGroup and Safran. This program, led by Pascal Chabert, initially launched in 2019, contributes to teaching activities and student projects around space, and to the École polytechnique Student Space Center (CSEP).
École Polytechnique, Inria, CNRS and Bañulsdesign have joined forces to launch the MATritime joint laboratory, with funding from the French National Research Agency. The aim is to develop computational and statistical tools that will provide the sea shipping industry with the tools for more sustainable boat design and operation.
Newly arrived at the Laboratory of Condensed Matter for Physics, Clément Livache conducts research on quantum dots, semiconductor nanocrystals whose light absorption and emission properties can be controlled. These are among the innovative materials that the interdisciplinary center Materials for Society (M4S) intends to promote.
In France, the cement industry emits 10 million tonnes of CO2 per year. The greenhouse gas comes from the manufacture of cement's active ingredient, clinker. At the Irradiated Solids Laboratory (LSI*), Marie-Noëlle de Noirfontaine and Mireille Courtial are carrying out detailed characterizations of materials likely to replace clinker. An essential step in the decarbonization of the industry.
Ten young researchers, most of them from École Polytechnique’s laboratories, presented their thesis topics at this event organized at École polytechnique by the Institut Polytechnique de Paris, of which École polytechnique is a founding member. Marie Sigallon and Elie Kadoche have been selected to represent IP Paris at the national semi-final to be held in April 2024.
The French Minister of the Armed Forces, Sébastien Lecornu, announced at École polytechnique the creation as early as summer 2024 of a new Ministerial Agency for Artificial Intelligence in Defense (MAAID). The agency's research center will be located on Ecole Polytechnique’s campus. The minister also reiterated the importance of the military status of École Polytechnique’s cadets, and underlined the importance of the resources allocated to École polytechnique by the Ministry of the Armed Forces.
Vincent Strubel (X2000), Director General of the French Cybersecurity Agency (ANSSI), spoke at École Polytechnique, underlining the change in scale of cybercrime, the explosion in training and research needs in cyberdefense, and the role Ecole Polytechnique can play to fulfill them.
