Zongjiyuan (Chengdu) Technology Co., Ltd. is located in the Sichuan Communications Industry Park in Wenjiang, Chengdu. Leveraging a research and development team of professors and doctoral researchers from the University of Electronic Science and Technology of China, the company focuses on the R&D of Maser‑based quantum sensing‑communication integrated technologies. In 2019, the company successfully developed the world's first room‑temperature transistor‑based microwave maser, breaking through traditional limitations such as cryogenic operation and optical pumping to enable direct excitation by weak electromagnetic fields. Building on this technology, the company has already created a range of quantum sensors for temperature, pressure, and other parameters, suitable for industrial sensing and IoT applications. Currently, the company is collaborating with numerous state‑owned and central enterprises, has completed field trials, and is poised to launch large‑scale commercialization.
