An international team headed by physicists from the Technical University of Munich (TUM) has, for the first time ever, experimentally implemented secure quantum communication in the microwave band in a local quantum network. The new architecture represents a crucial step on the road to distributed quantum computing.
As of yet, there are no universal quantum computers in the world. But for the first time, an international team led by TUM physicists Rudolf Gross, Frank Deppe and Kirill Fedorov has successfully implemented secure quantum communication in a local network - via a 35-centimeter superconducting cable. ...
