The QCI Days 2025 in Athens were a tremendous success! Together with our partners HellasQCI and EuroQCI Spain (MAD-QCI), and under the auspices of the Greek Ministry of Digital Governance, we welcomed an exceptional audience to the Eugenides Foundation from 28 to 30 April 2025.

Over three days, participants engaged in a rich programme featuring sessions on securing digital communication, industry panels on large-scale quantum network deployments, insightful use-case presentations, and discussions on standardisation and certification. Highlights included live demonstrations of quantum communication networks by HellasQCI, QCI-CAT, and EuroQCI Spain, interactive end-user discussions, inspiring company pitches, and a PETRUS workshop dedicated to ecosystem development.

We are incredibly grateful to all attendees for their active participation, to our partners for the excellent collaboration, and to all speakers for sharing their expertise and insights. The vibrant exchange of ideas and the strong engagement from policymakers, industry leaders, researchers, and EuroQCI stakeholders made this event an important milestone for advancing Europe’s quantum-secure communication infrastructure.

Thank you to everyone who contributed to making QCI Days 2025 such a success—we look forward to building on this momentum and seeing you at future EuroQCI events!
