The goal of BeQCI is to introduce, evaluate and develop quantum communication infrastructure (QCI) in Belgium. Our consortium  unites theoretical, experimental and engineering expertise on quantum technology, bringing together different university research groups, research centers, governmental agencies and private companies. BeQCI is part of the European EuroQCI initiative and is co-funded by the EU through the Digital Europe program and the Belgian Federal Science Policy Office (Belspo) through the Federal restart and transition plan. 

More details on the project can be found here. For an excellent introduction to quantum physics and its application in the context of quantum technologies like quantum communication & quantum key distribution, see the European Quantum Flagship portal.
