Researchers at Chinese Academy of Sciences have developed a "quantum router" that has been successful in running secure data transmission among four users guaranteed by quantum cryptography on a commercial network operated by Beijing Branch of China Netcom Group.
"The experiment was made in March, with the maximum and minimum distances between the nodes in the network being 32 and 42.6 kilometers, respectively. The researchers performed the quantum key distribution either between one and the other three users or between any two of them." According to CAS: "It is the only quantum network that could make simultaneous and two-way communications without any trusted relays ever reported in the world" Read more at: http://english.cas.cn/Eng2003/news/detailnewsb.asp?infoNo=26485 _______________________________________________ FDE mailing list [email protected] http://www.xml-dev.com/mailman/listinfo/fde
