"Photons Trained for Optical Fiber Obstacle Course Will Deliver Stronger Cyber Security"
The navigation of photons in networks of optical fibers will be improved through the use of a new technique demonstrated by researchers from the National University of Singapore (NUS) and Singtel, Asia's leading communications group. This new approach is expected to bolster cybersecurity as it improves quantum key distribution (QKD) over fiber networks. QKD is a secure communication method in which encryption keys are created through the detection of individual photons. This article continues to discuss the concept of QKD and the new approach to improving QKD over fiber networks.
