Deep in the Alps, ETH Zurich and Swisscom have implemented a fiber-optic link with Quantum Key Distribution (QKD) between Geneva and Zurich — spanning over 300 km — using encryption based on the laws of physics, not mathematical algorithms. ⚙️ How it works Entangled photons. Swisscom, Switzerland's leading telecom provider, has successfully tested a groundbreaking quantum-secure encryption method in partnership with German start-up Quantum Optics Jena (QOJ). This consortium of world-class academic, enterprise, and public institutions will advance quantum. um Industry Day, a consortium Geneva's first Quantique, Rolex and the Cantonal Office for Information Systems and the University of Geneva (UNIGE), CERN, HEPIA, ID Quantique, Rolex and the Cantonal Office for Information Systems and Digital Technology (OCSIN) announced the launch of a Geneva-based. By leveraging existing fiber optic infrastructure, the Geneva Quantum Network (GQN) will connect key institutions, enabling ultra-precise time distribution and pioneering experiments in quantum key distribution, laying the groundwork for unhackable communications and a thriving quantum technology. DIAMOND PS+ is our most advanced high power fiber optic connector interface, designed to handle up to 16W optical power on single mode fibers. Built with Graded Index Fibers (GIF) for superior beam expansion and optical performance, PS+ offers lower insertion and return loss compared to ball. Company sends quantum-encrypted data through 1,032-kilometer fiber-optic network at more than 10,000 times previous speed record. As a result, Terra Quantum sets world record in both, data transmission speed (keyrate) and data transmission distance. Approach utilizes conventional hardware.
