IonQ (NYSE: IONQ) has successfully deployed the technology for the Romanian National Quantum Communication Infrastructure (RoNaQCI), establishing one of the most extensive operational Quantum Key Distribution (QKD) networks in Europe. Spanning more than 1,500 kilometers across 36 quantum-secured links, the network accounts for over 20% of Europe’s total terrestrial quantum communications infrastructure to date. This project was delivered in partnership with the National University of Science and Technology POLITEHNICA Bucharest and RoEduNet, Romania’s national research and education network.
The nationwide network connects six major metropolitan hubs—Bucharest, Iași, Timișoara, Craiova, Cluj-Napoca, and Constanța—enabling secure data movement for government, healthcare, research, and education sectors. The architecture utilizes Wavelength Division Multiplexing (WDM) to transport encryption keys alongside data traffic in the C-band, demonstrating the scalability of quantum-secure communications within existing fiber-optic infrastructure. All QKD systems were supplied by IonQ’s subsidiary, ID Quantique, ensuring interoperability across the network’s metropolitan and terrestrial segments.
This deployment is a foundational component of the EuroQCI initiative, which aims to build a flagship quantum communication infrastructure across the European Union. IonQ’s recent expansion in Europe also includes the launch of the Geneva Quantum Network in Switzerland, a partnership with the Slovak Academy of Sciences, and the designation of Oxford, UK, as its EMEA headquarters. These initiatives follow IonQ’s 2025 technical milestone of achieving 99.99% two-qubit gate fidelity, reinforcing the company’s position in both quantum computing and secure networking.
