Develops

• OpenAI développe un smartphone dont la production débutera en 2028, où des agents d'IA remplaceront entièrement les applications traditionnelles pour les consommateurs américains. • L'appareil fait face à des obstacles potentiels liés aux pénuries mondiales de mémoire, ce qui pourrait retarder ou compromettre son déploiement. • Cette avancée pourrait perturber les écosystèmes mobiles dominés par Google et Apple, en redéfinissant les interfaces utilisateur.

• MIT scientists unveiled a new quantum computing design achieving stable operation of 1,024 qubits simultaneously, surpassing previous records and demonstrating significant error correction capabilities reported on April 21. • The innovation uses a novel topological qubit design with error rates of 0.1% per operation, enabling computations previously impossible due to quantum decoherence, according to research published in Physical Review Letters. • The breakthrough could accelerate commercial quantum computing applications in drug discovery, materials science, and optimization problems within 2-3 years, researchers said.

• Researchers at the University of Washington created an artificial photosynthesis prototype converting sunlight directly into storable chemical fuels with 13% efficiency, surpassing previous laboratory records of 8-10%. • The system uses engineered nanostructures and novel catalysts to split water and fix carbon dioxide, producing methanol as a liquid fuel suitable for existing energy infrastructure, detailed in Nature Energy on April 21. • The breakthrough could enable large-scale production of carbon-neutral synthetic fuels without competing for agricultural land, addressing both climate and energy security challenges.
