(原标题:台媒关注大陆建成全球首条量子通信线路:技术领先世界_《参考消息》官方网站)
参考消息网9月7日报道台媒称,世界上首条量子保密通信骨干网“京沪干线”,已完成量子保密通信及应用示范项目技术验收,达到开通条件。这将是史上跨度最大、最安全的通信网络。

据台湾中时电子报9月6日报道,“京沪干线”项目2013年7月由国家发改委批复立项,由中国科大作为项目建设主体,由安徽省、山东省投资建设并得到上海市、北京市的大力支持,经过42个月的艰苦努力,突破了高速量子密钥分发、高速高效率单光子探测、可信中继传输和大规模量子网络管控等关键技术,于去年底完成全线贯通,搭建了连接北京、济南、合肥、上海的全长2000余公里的量子保密通信骨干线路。
报道称,在最近半年多,相关人员进行各分系统的应用测试和720小时长时间稳定性测试,结果证明系统的各项技术性能指标都已达到设计要求,全线路密钥率大于20kbps,可满足万名用户的密钥分发业务需求。
