Quantum communications reaching record distances

The Cambridge Research Laboratory of Toshiba Europe announced a demonstration of quantum communications over optical fibres exceeding 600 km in length. The breakthrough will enable long distance quantum-secured information transfer between metropolitan areas and is a major advance towards building the future quantum internet. The term quantum internet describes a global network of quantum computers connected by long distance quantum communication links. It is expected to allow the ultrafast solution of complex optimization problems in … More
