From July 18 to 21, École Polytechnique hosted the International Physics Olympiad, the first time this event has been held in France since its inception in 1967. The event was an acknowledgement of École Polytechnique's eminent role in physics research and transmission. The event was also an opportunity to highlight the role played by women in key advancements of this scientific discipline.
For the third consecutive year, École Polytechnique hosted Opération CIEDS, an annual event dedicated to research and innovation in defense and security. The event, organized by the Center for Defense and Security Studies (CIEDS), in which many of the École Polytechnique's research laboratories are involved, is supported by the Ministry of the Armed Forces and the Defense Innovation Agency.
About 15 Bachelor's students got together under the guidance of Guillaume Dubach, Monge professor at École Polytechnique and member of the Laurent Schwartz Mathematics Center (CMLS), for two weeks of intro to math research in a summery, relaxed setting. This initiative was supported by École Polytechnique's “Pedagogy Dynamics” fund, financed by École Polytechnique Foundation.
Alain Aspect, a former student of the ENS-Cachan (now ENS-Paris-Saclay), professor at the Institut d'optique-université Paris-Saclay, professor at École polytechnique, and emeritus research director at the CNRS, was elected to the French Academy on June 26, 2025. He thus becomes the second French Nobel Prize winner in physics to be elected to the French Academy after Louis de Broglie, who won the Nobel Prize in 1929 and was elected in 1944.
The Institut Polytechnique de Paris, of which École Polytechnique is a founding member, is ranked 41st worldwide and 2nd in France in the QS 2026 ranking of world universities. The QS ranking covers 1,500 universities in 106 higher education systems.
The internationally renowned Slovenian mathematician Igor Klep is joining the Laboratory of Computer Science (LIX) and the Center for Theoretical Physics (CPHT) at École Polytechnique as a Gaspard Monge Visiting Professor. A professor of mathematics at both the University of Ljubljana and the University of Primorska in Slovenia, Igor Klep is collaborating on quantum information theory research with the PhIQus research group, led by Marc-Olivier Renou, INRIA Saclay Junior Professor Chair and affiliated researcher at LIX and CPHT.
Start-ups created by École Polytechnique's alumni or supported by X-UP, École Polytechnique's incubator, still account for a quarter of the list of 40 French Next40 start-ups, which has been thoroughly revised in 2025.
Of the eight start-ups incubated at École Polytechnique and present at VivaTech 2025, five have been selected for the Tech for Change 2025 program, which recognizes start-ups helping to address major contemporary environmental and societal challenges. Six École Polytechnique-incubated start-ups feature in VivaTech's Top 100 most promising start-ups in Europe.
Eight start-ups supported by X-Up, École Polytechnique incubator, are present at the VivaTech 2025 Show, alongside 16 other from from the incubators of other Engineering Schools of the Institut Polytechnique de Paris, of which École Polytechnique is a founding member.
École Polytechnique ranks 16th worldwide in this ranking of 200 higher education and research institutions worldwide that are training the future leaders in digital technology and artificial intelligence. École Polytechnique topped the list of 13 French institutions.
École Polytechnique hosted the 8th edition of Paris-Saclay Spring 2025, the annual entrepreneurship and research event on the Plateau de Saclay, one of the world's leading innovation and entrepreneurship hubs. Eight start-ups supported by X-UP, the École polytechnique's incubator, or stemming from its research ecosystem, are among the 50 young companies selected as the most promising on the Plateau de Saclay. One of them, Plasana Médical, is the winner of the Spring 50 competition.
The École polytechnique incubator is launching its 1st network events, Ecosystem Days, themed and open to all innovation players. On 30 November, the first event will focus on intellectual property and legal issues. We look forward to seeing you there!
