A team led by Han Zhengfu and Chen Wei, members of the academician Guo Guangcan's group at the University of Science and Technology of China, in collaboration with Professor Xue Kaiping and others, has made significant progress in the field of heterogeneous quantum network construction. On December 12, 2025, the relevant research findings were published in Nature Communications. Currently, quantum networks are often designed as dedicated systems for specific tasks, which restricts the openness and diversity of the quantum internet. To address this, the research team proposed a heterogeneous quantum communication network architecture and introduced software-defined networking technology, designing an 'orchestration core' and successfully constructing and operating a five-node heterogeneous quantum network. This network not only achieved multi-switching but also completed the verification of four quantum tasks. Moreover, it demonstrated, for the first time internationally, a quantum Byzantine agreement involving multiple malicious nodes. This fully heterogeneous network scheme significantly enhances network flexibility, providing a blueprint for prepare-and-measure quantum networks and offering a crucial example for the widespread interconnection of the quantum internet.
