Latvia and Lithuania formally launched the Lat-LitQN project to develop a cross-border quantum communication infrastructure, as reported by Xinhua on March 10, 2026. The project is funded by the European Union under the Connecting Europe Facility (CEF) for telecommunications and coordinated by the Latvian telecommunications company Tet.
Partners include Kaunas University of Technology (KTU), Vilnius University, the Institute of Mathematics and Computer Science of the University of Latvia, and the European academic network GÉANT. The planned network will span approximately 300 kilometers, linking the cities of Riga, Panevėžys, and Vilnius.
According to KTU, the project runs from January 2026 through December 2028. Participating institutions plan to develop quantum communication solutions for secure data transmission in sectors including healthcare, finance, energy, and public administration. Prof. Šarūnas Grigaliūnas of KTU described the work as preparing “technical requirements for cross-border passive infrastructure” and forming “the basis for a reliable and secure quantum communication connection between Latvia and Lithuania.” The project ranked among the three highest-rated cross-border proposals in the CEF program, which funded 19 new cross-border projects across Europe.
