Qubit modules (IMAGE) Max-Planck-Gesellschaft Caption This picture shows the two qubit modules (red atom between two blue mirrors) that have been interconnected to implement a basic quantum computation (depicted as light blue symbol) over a distance of 60 meters. The modules reside in different laboratories of the same building and are connected by an optical fiber. The computation operation is mediated by a single photon (flying red sphere) that interacts successively with the two modules.
