(Phys.org) A team of researchers from the Department of Energy’s Oak Ridge and Los Alamos National Laboratories has partnered with EPB, a Chattanooga utility and telecommunications company, to demonstrate the effectiveness of metro-scale quantum key distribution (QKD) as a means of secure communication for the nation’s electricity suppliers. This initial milestone is part of the team’s three-year project focused on next-generation grid security.
Ray Newell, Los Alamos research scientist and leader of their quantum communications team: “Recent demonstrations at Los Alamos have shown that QKD systems can operate on existing electric infrastructure in real-world settings, including during a historic snowfall. Our partnership with ORNL and EPB shows that utilities can realize the benefits of quantum security using a mix of distinct but interoperable communication systems.”
