In 2025, Beijing officially unveiled 16 major quantum technology achievements, marking China’s entry into the global forefront of quantum information science. These breakthroughs span three core areas: quantum computing, quantum communication, and quantum precision measurement. Key highlights include performance advances in superconducting quantum chips, deployment of a metropolitan-scale quantum key distribution (QKD) network, and a prototype high-precision quantum gravimeter. Notably, a 100-qubit superconducting quantum processor developed by the Beijing Academy of Quantum Information Sciences achieved single-qubit gate fidelity of 99.9% and two-qubit gate fidelity of 99.5%, laying a solid foundation for practical quantum computing. Meanwhile, the upgraded Beijing–Xiong’an quantum communication backbone now supports secure key distribution over distances exceeding 1,000 kilometers, significantly enhancing national cybersecurity. Several innovations, such as quantum random number generators and quantum radar prototypes, have entered early-stage commercialization and are poised for initial deployment in finance, defense, and geospatial surveying. These milestones underscore Beijing’s role as a global hub for scientific innovation and provide robust support for China’s goal of building an independent and controllable quantum technology ecosystem.
