IonQ deploys Romania's national quantum communication infrastructure (RoNaQCI), one of Europe's largest QKD networks
On 2026-02-26 IonQ announced it had deployed the technology powering Romania's National Quantum Communication Infrastructure (RoNaQCI), described as one of the largest operational quantum-key-distribution (QKD) networks in Europe: 36 quantum-secured links spanning more than 1,500 km and connecting six metropolitan areas (Bucharest, Iasi, Timisoara, Craiova, Cluj-Napoca, Constanta), accounting for over 20% of Europe's terrestrial quantum-communications infrastructure. The project was delivered with POLITEHNICA Bucharest and RoEduNet, with QKD systems supplied by IonQ's ID Quantique subsidiary.
A deployed national-scale QKD network is one of Europe's largest operational quantum-communications builds and a concrete, principal-confirmed reference-and-revenue win for IonQ's networking/ID Quantique business; the scale and national-infrastructure status clear into the material band.
National QKD infrastructure validates quantum-secured communications at scale for government and critical-infrastructure customers and entrenches IonQ's European networking footprint via ID Quantique; the long-run question is QKD's role versus standardized post-quantum cryptography.
