"Researchers Achieve Quantum Key Distribution for Cybersecurity in Novel Experiment"
Researchers at the Department of Energy's (DOE) Oak Ridge National Laboratory have shown that advanced quantum-based cybersecurity can be implemented in a deployed fiber link. Their findings validate an earlier proof-of-principle laboratory experiment conducted by ORNL scientists in 2015. The team used a true local oscillator to transmit a quantum signal for Quantum Key Distribution (QKD), a secure secret key-sharing method. A local oscillator suppresses the effects of noise scattered from other data transmitted in the same fiber-optic network. The study showed the coexistence between the quantum and conventional data signals. This article continues to discuss the achievement of QKD for cybersecurity in a novel experiment.
