The DRF at the CEA assemble approximately 6,000 scientists since January 2016.
Researchers at the CEA-Irig have demonstrated that there is an optimal configuration for bringing the coherence times of hole spins closer to those of electron spins.
Nine months after its launch, the James Webb Space Telescope (JWST) has provided unprecedented images of an exoplanet. The first ever obtained in the mid-infrared, these images should revolutionize our knowledge of extrasolar planets. French astronomers, including some from the CEA-Irfu, participated in observing this planet and in designing the telescope coronagraphs.
Researchers at Irig and their partners have demonstrated for the first time that it is possible, through the simple application of a gate voltage, to change the winding direction of magnetization “nano-vortices” (skyrmions), and thus to individually control the direction of their motion. This breakthrough opens up new possibilities for research in information processing (multiplexing, etc.).
An international collaboration involving the LSCE (CEA-CNRS-UVSQ) recommends the earliest possible deployment of these technologies on a large scale. If postponed to the latter half of this century, the available biomass production would be largely reduced by climate change, jeopardizing the goal of containing global warming to 2°C by 2100, and potentially leading to food shortages.
Researchers from the CEA-Iramis and their partners at the Laboratoire de Mécanique des Fluides de Lille have been exploring the origin of irreversibility through a unique large-scale turbulence experiment.
CEA and RIKEN have been working together in the field of AI, big data and HPC for more than five years.
A method known as quantum key distribution has long held the promise of communication security unattainable in conventional cryptography. An international team of scientists has now demonstrated experimentally, for the first time, an approach to quantum key distribution that is based on high-quality quantum entanglement — offering much broader security guarantees than previous schemes.
Researchers at the CEA-Joliot (NeuroSpin) have succeeded in systematically decoding the cognitive activity associated with various brain activation patterns as recorded by functional MRI. This feat was achieved using neural networks trained on the largest public brain imaging database.
Based on experiments conducted in the European tokamak JET, physicists from the IRFM and their partners demonstrated that the increased presence of highly energetic deuterium ions improves the stability of the fusion plasma. ITER’s plasma should benefit from a similar effect, thanks to the helium nuclei produced by fusion.

CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
