Denmark signed the European Quantum Communication Infrastructure (EuroQCI) Declaration in early 2020, joining Austria, Bulgaria, Romania, and the Czech Republic in the latest group of signatories. The declaration, originally launched in June 2019 at the Digital Assembly in Bucharest, committed participating EU member states to working with the European Commission and the European Space Agency on the design, development, and deployment of a quantum communication infrastructure across the EU.
Simon Kollerup, Denmark’s Minister of Industry, Business and Financial Affairs, said the development of quantum technologies creates “both new possibilities and new challenges,” according to the European Commission announcement. By joining the initiative, Denmark agreed to contribute to a secure communication infrastructure that would protect national and cross-border critical infrastructure, sensitive government communications, and financial transactions using quantum key distribution technology.
Denmark’s signature brought the total number of participating member states to 24 at the time. All 27 EU member states eventually signed the declaration by July 2021.
