A rudimentary quantum network link between Dutch cities
QuTech has demonstrated a network connection between quantum processors over metropolitan distances. Their result marks a key advance from early research networks in the lab towards a future quantum internet.
Researchers around the globe are working to build quantum networks that make use of these features to offer fundamentally new communication and computing capabilities, in coexistence with the current internet. We had to design a flexible system that lets the nodes work independently over long distances, we needed to mitigate the impact of photon loss on the connection speed, and we had to ensure reliable confirmation each time the entanglement link was successfully created. Co-author Kian van der Enden explains how indispensable the broad expertise of the team was for the success of the project: “Fraunhofer ILT developed a critical component for this demonstration, a new type of quantum frequency converter.
