In 2019, Luxembourg signed a declaration with six other EU countries (Belgium, Germany, Italy, Malta, the Netherlands & Spain) agreeing to explore the potential for a quantum communication infrastructure (QCI) across Europe.
The benefits of QCI boil down to extremely high levels of security, enabled through both earth- & space-based components. Eventually, it would facilitate Europe’s quantum internet, connecting quantum computers, for example. Though still in the early stages, participants are working together with the EU Commission to first examine how QCI should be designed in the context of user requirements.
