QCI Insights and Single-Photon Awareness Forum
16 – 17th of September 2025
Tallinn area, Estonia
Our efforts in developing QCI infrastructure continue to advance through deployment and testing. Therefore, it’s the perfect moment to come together as a community to reflect on our progress. Each of our initiatives have its unique experiences, challenges, and triumphs — and now is the time to share these insights with our colleagues across Europe.
The EstQCI project is proud to invite representatives from across Europe to join us for a two-day event that will serve as a platform for collaboration, knowledge sharing, and networking. This forum offers an invaluable opportunity to learn from each other’s challenges and successes, fostering a cooperative environment where we can grow together.
Throughout the event, we will reflect on the experiences gained from our respective projects, discuss lessons learned, and explore new strategies for overcoming common obstacles. With a focus on practical experiences, we will look ahead to the next stages in the EU-wide plans, identifying opportunities for further collaboration and alignment as we continue to build the quantum communication infrastructure of the future.
This event is not only an opportunity to exchange knowledge but also a chance to deepen connections with peers, partners, and stakeholders who share the same vision of a connected and secure quantum-enabled Europe. Join us as we work together towards making these ambitious plans a reality.
The event takes us away from the Tallinn City Centre to a seaside LaSpa hotel where we can focus on sharing experiences and build collaborations in a beautiful and relaxing environment.
