The first compact P-band high-power metamaterial klystron for the linear accelerator of China's Spallation Neutron Source has passed various index tests and been successfully accepted. This is the world's first successfully developed high-power metamaterial klystron. After more than four years of technical research, the R&D team first adopted the technology of loading metamaterials into the resonant cavity and designed a 324-megahertz high-power klystron. "While its main technical indicators reach the international advanced level, the volume of the cavity string structure is reduced by about 50% compared with similar foreign devices, and the cost is also lowered."
The first 6-inch thin-film lithium niobate photonic chip wafer rolled off the production line at China's first photonic chip pilot line. Meanwhile, large-scale mass production of high-performance thin-film lithium niobate modulator chips with ultra-low loss and ultra-high bandwidth was achieved, with key technical indicators reaching international advanced levels. This provides core hardware support for quantum computing and 5G communications.
The research team of the University of Science and Technology of China innovatively uses the Martian atmosphere for power generation and energy storage, with the power - generation efficiency increased by 20%. The "Martian Gas Battery" can supply power stably at 0¡æ, and the waste heat can be used for heating and fuel production. The simultaneously broken - through controlled nuclear fusion technology has achieved a reaction temperature of 160 million degrees, and the two technologies are outlining a new picture of the energy revolution.
A Chinese scientist team has combined behavioral experiments with neuroimaging analysis to first confirm that multimodal large language models based on artificial intelligence (AI) technology can spontaneously form an object concept representation system highly similar to that of humans – that is, AI can spontaneously develop human - level cognition. The related research paper was published online in the international professional academic journal Nature Machine Intelligence on June 9. This not only opens up a new path for AI cognitive science but also provides a theoretical framework for constructing AI systems with human - like cognitive structures.
The China Academy of Information and Communications Technology announced that the total number of 5G base - stations in China has reached 4.439 million, . The number of 5G mobile phone users in China has reached 1.081 billion. 5G coverage has been achieved in every township, and the proportion of administrative villages with 5G coverage has reached 90%.
At the same time, the mobile communication network is accelerating its evolution and upgrade to 5G - A, and 5G - A networks have been deployed in more than 300 cities.
5G applications have been integrated into 86 out of 97 major categories of the national economy, with a total of more than 138,000 cases. The number of “5G + Industrial Internet” construction projects nationwide exceeds 18,500.
