The system launched in February and recently achieved first light. It will join Japan's orbiting QZSS satellite constellation to…...

2+ hour, 48+ min ago   (615+ words) Insider Brief PRESS RELEASE — When the scientific community discusses quantum computers, it is usually the question of the underlying system that causes division. Ion traps, Rydberg atoms, or perhaps superconducting circuits? At Leibniz University Hannover, Dr Kai Voges has launched…...

7+ hour, 36+ min ago   (77+ words) The program comes at a time when optical connectivity is becoming critical infrastructure for AI and high-performance computing. LightCounting further estimates that the market for optical chips used across transceivers, active optical cables and near- and co-packaged optics could grow…...

3+ hour, 56+ min ago   (317+ words) The US Department of Defense has selected four directed energy systems for a counter-drone pilot that will test how lasers and high-powered microwaves perform in real-world operations. Lasers can engage drones using electrical power rather than conventional ammunition, while high-powered…...
