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”.
In an article published in the journal Science, an international collaboration involving researchers from the Centre for Theoretical Physics (CPHT*) proposes a tool for estimating the difficulty of many problems yet to be solved, as well as the effectiveness of methods developed to tackle them, including quantum algorithms.
Theoretical physicist Carlota Andres and economist Julien Combe are the winners of two ERC Starting Grants supported by Ecole Polytechnique. This funding from the European Research Council helps early-career researchers to build their teams and pursue their most ambitious ideas.
Balt van Rees, a researcher at the Center for Theoretical Physics, is interested in the mathematical framework of quantum field theories, which are used in many areas of physics, still raises many questions. He is leading the QFTinAdS project funded by the European Research Council.
Camille Duprat (Hydrodynamics Laboratory), Roland Rathelot (Centre for Research in Economics and Statistics), Balt Van Rees (Centre for Theoretical Physics) and Maks Ovsjanikov (Computer Science Laboratory of the École Polytechnique) are carrying out projects funded by the European Research Council.
Antoine Georges, physicist at the Centre for Theoretical Physics and Professor at the Collège de France, has been awarded the Feenberg Memorial Medal along with Gabriel Kotliar and Dieter Vollhardt for his theoretical work on quantum systems consisting of a large number of interacting particles.
On March 21 and 22, the conference "Aspects of Gravity, Mathematics and Physics" took place. It was organised by the Laurent Schwartz Mathematics Center and the Center for Theoretical Physics for scientists to discuss issues related to gravitation as well as the theory of general relativity and its extensions.
At LULI, laser beams are amplified and used for nuclear fusion experiments, among other studies. On 18 August, the National Ignition Facility (NIF) at...
