The prototype of the CR450 high-speed rail train, the world's fastest high-speed rail train, has been Taken offline, with a designed speed of up to 400 kilometers per hour. Currently, the R&D team is conducting a number of experimental verifications. The China State Railway Group plans to complete the relevant assessments in 2025.
The 2025 Global Developers Pioneer Conference opened in Shanghai. The humanoid robot G1 and the quadruped bionic dog Go2 of Unitree Technology, made their debut at the exhibition site. The humanoid robot demonstrated actions such as running and even picked up a rope to walk the bionic dog. This magical scene of "a humanoid robot walking a bionic dog" attracted a large number of spectators to stop and watch.
The Beijing Academy of Quantum Information Sciences, in collaboration with teams from Tsinghua University and North China University of Technology, proposed the theory of one-way quantum direct communication and developed a practical system. They achieved quantum direct communication over a distance of 100 kilometers for 168 consecutive hours, with the communication rate remaining stable at 2.38 kilobits per second. This rate is comparable to the technical specifications of the first-generation mobile communication technology (1G), setting a world record for the quantum direct communication rate over a distance of 100 kilometers. The relevant achievements were published in Science Advances, marking that this technology has stepped into the stage of practical application.

The scale of Shanghai's artificial intelligence industry exceeded 450 billion yuan in 2024,with a YOY growth of over 7.8%, and 60 generative AI large models have been filed accumulatively. According to the Implementation Plan of Shanghai on "Modeling Shanghai" in the Field of Artificial Intelligence, by the end of 2025, Shanghai will build a world-class artificial intelligence industry ecosystem, covering aspects such as computing power, corpus, models and applications.
At the Symposium on Artificial Intelligence and Robot Enterprises in Chengdu city, the Municipal Public Security Bureau released application scenarios, and multiple departments are assisting in the industrial development. Chengdu has already introduced relevant policies, leading to the expansion of the industrial scale. Enterprises offered suggestions focusing on finding application scenarios, building platforms, attracting talents, etc. Chengdu will deepen the application of scenarios, establish a collaborative innovation model, and create a highland for industrial development.
