Building on last year’s success, this year’s demo will be even more spectacular, showcasing advanced quantum key distribution capabilities and interoperability across domains, highlighting the progress and innovation driving Europe’s quantum communication landscape.

Copenhagen, 28 September-2 October 2025

The QCI-CAT project is excited to participate in QCI Connect 2025, taking place from September 16 to 17 near Tallinn. We look forward to the “Experience Exchange & Project Insights” program, which will include presentations by NatQCI country representatives sharing deployment status, pilot implementations, lessons learned, and technical challenges such as vendor coordination, regulatory hurdles, and integration with classical infrastructure. The event will also feature interactive sessions focused on practical experiences, tools, processes, and peer-driven project optimization, as well as discussions on CEF Digital call alignment to foster cross-project collaboration within the EuroQCI ecosystem. This will be an excellent opportunity to exchange knowledge, strengthen collaboration, and contribute to the advancement of quantum communication infrastructure across Europe

The QCI-CAT project is excited to participate in the ARES 2025 Conference, where it organized the SECPID – 6th Workshop on Security, Privacy, and Identity Management in the Cloud together with the projects LICORICE and CASTOR. Join us for engaging discussions on advancing security, privacy, and identity management in the evolving quantum communication landscape!

Ghent, 11 August 2025

The QCI‑CAT project is proud to announce that we will be presenting our Video Chat and HSM Backup use‑case demonstrations—developed in collaboration with AIT, CANCOM, and X‑Net—at the upcoming International Digital Security Forum (IDSF) 2025 in Vienna (June 4–6) idsf.io.

Visitors to our booth can look forward to seeing our compact, multi-node setup featuring the open‑source WireGuard VPN extension “Arnika.” This demo not only showcases quantum‑key‑protected HSM backup over a QKD‑enabled network but also the integration of QKD-generated keys into secure video conferencing sessions with combined post‑quantum encryption qkd-kms.ait.ac.at. Beyond hands‑on interactions, attendees will gain insight into key performance benchmarks—such as key request intervals of ~200 ms and minimal system resource usage—proving the robustness and practicality of our solutions qkd-kms.ait.ac.at.

Join us at IDSF to explore cutting‑edge quantum‑secured networking, engage with experts from public authorities, industry, and research, and discover how our QCI‑CAT demonstrators are advancing digital security, sovereignty, and trust in the quantum communication era.

The QCI-CAT project is excited to co-organise QCI Days Athens 2025 together with HellasQCI and EuroQCI Spain (MAD-QCI). The event—taking place from 28 to 30 April 2025 at the prestigious Eugenides Foundation in Athens—is hosted under the auspices of the Greek Ministry of Digital Governance and co-organised equally by GRNET, AIT (QCI-CAT), and UPM (EuroQCI Spain) (hellasqci.eu).

Participants can look forward to a rich programme shaping the future of the pan-European Quantum Communication Infrastructure (EuroQCI). The agenda includes sessions on securing digital communication, industry panels on large-scale quantum network deployments, use-case presentations, technology showcases, and discussions on standardisation and certification. Attendees will also experience live demonstrations of quantum communication networks by HellasQCI, QCI-CAT, and EuroQCI Spain, interactive end-user discussions, company pitches, and a PETRUS workshop focused on ecosystem development.

Registration for speakers and attendees is free but mandatory. Details and the full agenda are available on the QCI Days website, where participants can also sign up for this key event. Join us in Athens to engage with policymakers, industry leaders, researchers, and EuroQCI stakeholders, and be part of shaping the future of quantum-secure communication in Europe!

The QCI-CAT project is excited to announce its participation in the 1st KIRAS and K-PASS (KuK) Symposium taking place from 11–12 November 2024 in Vienna (kiras.at). Together with our partner X-Net, AIT will present our quantum-secured video chat demo, showcasing how cutting-edge quantum communication technology is driving both the EuroQCI initiative and Austria’s national security research efforts.

Over two days, participants can look forward to engaging presentations, expert discussions, and live demonstrations highlighting innovative security solutions. Our contribution will demonstrate how quantum communication and post-quantum cryptography can be seamlessly integrated into practical, secure communication systems—positioning Austria at the forefront of European and national digital security advancements.

Join us at this important event to connect with experts, explore the intersection of EuroQCI and national security research, and see our demo in action!

The QCI‑CAT project is delighted to announce its participation at ECOC 2024 in Frankfurt (22–26 September 2024), where it will join forces with PETRUS and other leading EuroQCI stakeholders to deliver a live, multi‑vendor Cross‑Domain QKD demonstration. Organized by PETRUS, the “Mini EuroQCI” showcase features three independent QKD domains—Spain, Germany, and Austria—powered by various QKD vendors and Key Management Systems, seamlessly integrated into a unified network

During the three days of demonstration, attendees will be able to experience quantum-secured video conferencing and a quantum lottery application, fully encrypted using keys exchanged across domains via interoperable protocols and encryption layers. The participation of QCI‑CAT and PETRUS aims to underscore the maturity and real-world readiness of EuroQCI technologies, showcasing how QKD systems can be interoperable, vendor-agnostic, and integrated into end-user applications.

Join us in experiencing how Europe’s quantum-secured infrastructure is taking shape—demonstrating not only technical interoperability and network scalability, but also a clear path toward quantum-secure communication services for critical infrastructure across Europe.
