The National Quantum Communication Infrastructure (HellasQCI) is a cutting-edge project that integrates Greece into the European EuroQCI initiative, aiming to develop communication networks that offer top security through quantum technologies.
The central technology of the project is Quantum Key Distribution (QKD), which utilizes the principles of quantum physics to create and transmit cryptographic keys in an unbreakable manner. This means that any eavesdropping attempt is immediately detected, ensuring absolute data protection.
HellasQCI combines:
- Ultra-secure optical fibers for the transmission of quantum keys.
- Quantum nodes and QKD devices for the implementation of secure connections.
- Integration with existing network infrastructures to support critical services of the public and private sectors.
With the implementation of HellasQCI, Greece fortifies government communications and critical infrastructures, enhances cybersecurity at national and European levels, and lays the foundation for innovative applications in areas such as defense, health, and financial services.
This project represents a strategic step for the country's digital sovereignty and the utilization of technologies that will define the future of communication security.
The National Quantum Communication Infrastructure HellasQCI is already operating on a pilot basis since 2025. The network connects key points in Athens, Thessaloniki, and Heraklion, utilizing more than 650 kilometers of optical fibers and quantum encryption technologies (QKD), and is part of the pan-European EuroQCI initiative, aiming for full development and operation by 2030. The installation of such infrastructures enhances the country's digital sovereignty and positions Greece at the forefront of next-generation technologies in the Eastern Mediterranean.
