Participation in the HellasQCI Winter School provides a valuable opportunity to introduce individuals to key aspects of quantum communications. Practical experience will be offered in the implementation and use of Quantum Key Distribution (QKD) technologies, including both terrestrial and space-based systems. The programme is designed to facilitate networking with leading experts and stakeholders across Europe’s quantum ecosystem. Opportunities will be provided to contribute to national and cross-border collaboration efforts, while directly participating in discussions on Greece’s national roadmap for quantum technologies, within the broader context of the European Quantum Communication Infrastructure (EuroQCI) and the shared objective of advancing European quantum sovereignty.
