Wits researchers achieve major leap forward in secure quantum communication

University of the Witwatersrand (Wits) scientists have achieved a major advance in the field of secure quantum communications, the university announced on Friday. The team, led by School of Physics Professor Andrew Forbes, has had its research paper published online by Laser & Photonics Reviews. The team set a new record for the number of parties to whom information could be securely and simultaneously sent by means of quantum communication. “In traditional secure quantum communication, information is sent securely from one party to another, often named Alice and Bob,” noted Forbes. “In the language of networks, this would be considered peer-to-peer communication and by definition has only two nodes: sender and receiver.”
