At the Digital Assembly held in Bucharest, Romania, representatives of 7 EU Member States (Belgium, Germany, Italy, Luxembourg, Malta, the Netherlands, and Spain) signed a declaration agreeing to explore together, over the next 12 months, how to develop and deploy a quantum communication infrastructure (QCI) across the EU within the next decade. This infrastructure would enable information and data to be transmitted and stored ultra-securely, and link communication assets all over the EU. The QCI would integrate quantum technologies and systems into conventional communication infrastructures, and consist of two elements: an earth-based component making use of existing fibre communication networks linking strategic sites at national and cross-border level, and a space-based component to cover long distances across the EU and other continents.
