Description
The HUB subproject combines three subprojects. The common goal is to generate and verify entanglement of three quantum storage nodes using entangled photons from a third node. Bridging a distance of 52 km via a fiber test link is a key demonstrator for a quantum repeater in a metropolitan region and future networking of quantum computers. The goals for each subproject are listed below.
