Those are not exactly the same. The Rolls Royce reactor is much smaller at like 10 MW.
It would be much closer to the nuclear reactor that China is supposed to use for its 'mini-nuke' submarines.

Then again I would not put much credence into Rolls Royce's efforts. They have been pushing SMRs for like two decades at this point. But nothing ever gets built in Britain.

84.2% of smartphones sold in China in May has 5G function.

China is aiming to deploy 5G-A commercial services in 300 cities by the end of this year and full commercialization of 5G-A by the end of 2026.
5G-A technology is maturing, Yicai learned at the three-day MWC Shanghai, which attracted over 8,000 companies from 115 countries and regions and ends today. More than 30 global operators have completed 5G-A technology verification and around 10 have announced commercial plans for 5G-A, while several models from about 20 phone brands support the feature's default activation.

China Mobile will phase in the construction of 5G-A networks, planning to deploy commercial 5G-A services in 300 cities by the end of this year, Deputy General Manager Li Huidi told Yicai. It aims to achieve large-scale 5G-A services by next year and full commercialization by 2026, he added.

Shanghai Institute of Microsystem and Information Technology has realized an ultra-high-speed, photon-number-resolvable photon quantum detector​

  
Recently, the team of Li Hao and You Lixing from the Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences, used sandwich-structured superconducting nanowires and multi-wire parallel operation to realize an ultra-high-speed, photon-number-resolvable photon detector with a maximum counting rate of 5 GHz and a photon number resolution of 61. The related results were published online on May 31, 2024 in the first-tier academic journal Photonics Research of the Chinese Academy of Sciences under the title "Superconducting single photon detector with speed of 5 GHz and photon number resolution of 61" (
