On December 11, 2025, at UPJ\u0160 in Ko\u0161ice, in the premises of the Center for Applied Informatics PF UPJ\u0160, located at Jesenn\u00e1 5, connecting Ko\u0161ice and Pre\u0161ov<\/strong>. This is a historic milestone in the construction of the national quantum communication infrastructure and also the first fully functional element of the Slovak network<\/strong>, which is part of the pan-European EuroQCI<\/strong> project.<\/p>\r\n\r\n\r\n\r\n

Slovakia is thus joining the countries actively developing second-generation quantum technologies<\/strong> \u2013 technologies that will enable not only secure communication but also the transfer of quantum information between quantum computers in the future. The Slovak quantum network is being created as a part of the national project skQCI<\/strong>, which is a part of the European initiative EuroQCI<\/strong> (European Quantum Communication Infrastructure). A broad platform of partners who have signed the Memorandum on Support for the Development of Quantum Communication Infrastructure in Slovakia<\/strong> is also contributing to the development of quantum infrastructure. The signatories include universities, research institutions, public authorities, and technology partners<\/strong>. The memorandum creates a framework for a coordinated action in the introduction of quantum technologies, the interconnection of public institutions via secure quantum links, and the sharing of know-how across the sector. The ceremonial opening of the first link between Pavol Jozef \u0160af\u00e1rik University in Ko\u0161ice and the University of Pre\u0161ov in Pre\u0161ov is a concrete result of this joint initiative.<\/p>\r\n\r\n\r\n\r\n

\r\n\u201eAmong other things, this quantum line provides an excellent opportunity for our faculty and university to enrich teaching with practical demonstrations and conduct a new type of research in the fields of quantum computing and cyber security. This new stimulus has reinforced the faculty’s intention to create a new study program focused on quantum technologies.\u201c\r\n\r\nprof.

Before the ceremonial launch of the line between Ko\u0161ice and Pre\u0161ov, secondary school students had a unique opportunity to see a live demonstration of this quantum connection in the morning. During the demonstration, a group of students from the Secondary Industrial School of Electrical Engineering in Pre\u0161ov connected with nearly 200 students present in the UPJ\u0160 auditorium in Ko\u0161ice as part of the Focus on Nobel Prizes event, organized annually by the Faculty of Science of Pavol Joze\u0161 \u0160af\u00e1rik University in Ko\u0161ice.<\/p>\r\n\r\n\r\n\r\n
