Led by Pan Jianwei from the University of Science and Technology of China, the research was conducted by a group of scientists over the past few years. Reviewers of the study hailed the achievement as "impressive" and "futuristic", as it is the largest of its kind in the world. It also represents a major step toward building a practical, large-scale quantum internet, they added. In the quantum network, several services such as video call, audio call, fax, text transmission and file transmission have been realized for technological verification and real-world demonstrations, the paper noted, adding commercial use is expected in the near future.
在中国科学技术大学潘建伟的带领下，科学家们为此进行了数年研究。《自然》杂志审稿人评价称，这是地球上最大的量子密钥分发网络，这一成就“令人惊叹”且“具有前瞻性”，也代表着科学家朝着构建实用性广域量子通信网络迈出了重要一步。研究人员在论文中指出，在量子通信网络领域，视频通话、音频通话、传真、文本传输和文件传输等多项服务已实现技术验证和实用展示，预计不久将用于商业用途。
