The Science
A team from Oak Ridge and Los Alamos National Laboratories led a demonstration of quantum key distribution systems that harness the power of quantum mechanics to authenticate data and encrypt messages with a secret ”key” to securely transmit “locked” information from one QKD system to another. The researchers placed their systems and a new system developed by industrial partner Qubitekk in electrical substations throughout Chattanooga to demonstrate the potential to expand QKD’s range as well as the interoperability of different systems across a fiber-optic network created by EPB, a utility and communications company.
The Impact
Distance limitations previously prevented QKD from becoming a viable addition to existing grid management techniques, but this test proved that three distinct systems can complete a real-world relay of quantum keys. In addition to other successes, this increased range could help improve the cybersecurity, longevity and efficiency of the power grid on a national level.
