CZQCI Completes 3-City Quantum Backbone, Securing Data Across Prague, Brno and Ostrava
1 articles · Updated · Quantum Zeitgeist · Jul 23
Summary
CZQCI said its completed quantum-communication backbone has carried secure data end-to-end across Prague, Brno and Ostrava, marking an operational milestone beyond a project announcement.
The 2023-2027 program is building a quantum-key-distribution network so Czech government bodies and critical institutions can exchange encryption keys protected by quantum physics.
CyberSecurityHub coordinates the network with partners including Masaryk University, Brno University of Technology, Czech Technical University in Prague and IT4Innovations, tying the system into a wider national research infrastructure.
The backbone also plugs the Czech Republic into Europe’s broader quantum-communication initiative, complementing the country’s 24-qubit VLQ quantum computer in Ostrava and its infrastructure-led quantum strategy.
Is the new quantum communication backbone strong enough to defend against 'harvest now, decrypt later' cyberattacks?
As America backs private firms, can Europe’s public infrastructure model keep pace in the global quantum technology race?
CZQCI Quantum Backbone Connects Prague, Brno, Ostrava: Czech Republic’s Leap Toward Quantum-Secure Communication and European Digital Sovereignty
Overview
On April 14, 2026, the Czech Republic launched its National Quantum Communications Infrastructure (CZQCI), creating a secure quantum backbone that connects Prague, Brno, and Ostrava. This achievement marks a crucial first step in building advanced, secure communication networks using quantum technologies. The project is the result of a broad collaboration among academic, research, and government partners, with CyberSecurityHubcz playing a key coordinating role. Importantly, CZQCI is not just a national effort—it forms the foundation for the larger EuroQCI initiative, making the Czech Republic’s launch a vital contribution to Europe’s vision for enhanced digital security.
