Lithuania signed the European Quantum Communication Infrastructure (EuroQCI) Declaration in December 2019, joining eight other EU member states in that round of accessions. According to the European Commission, Croatia, Cyprus, Greece, Finland, France, Lithuania, Slovakia, Slovenia, and Sweden all signed the declaration at the end of 2019.
Simonas Šatūnas, Lithuania’s Deputy Permanent Representative to the EU, said at the time that the country was joining with “a strong belief that new quantum technologies are already shaping our digital future.” He added that member states together are “better prepared to explore how these technologies could make our communication infrastructure more secure and data storage and the exchange of information safer.”
The EuroQCI Declaration had been launched in June 2019 at the Digital Assembly in Bucharest, initially signed by seven member states. Signatory countries committed to working with the European Commission and the European Space Agency to develop and deploy a quantum communication infrastructure across Europe within ten years, encompassing both terrestrial fiber-optic and satellite-based segments.
