Arqit, Es’hailSat, and AIEE Successfully Demonstrate Quantum-Safe Satellite Security in Qatar

Arqit Quantum Inc., a global leader in quantum-safe encryption; Es’hailSat — the Qatar Satellite Company — a world-class satellite operator and service provider spanning the MENA region; and Advanced International Electronic Equipment Company [AIEE], a specialist systems integrator for secure communications infrastructure, announced the successful demonstration of quantum-safe security across operational satellite communications infrastructure.

The collaboration highlights a practical method for satellite operators and critical infrastructure providers to enhance communications resilience against emerging quantum threats without interrupting live operations. As governments and infrastructure operators prepare for the cybersecurity impacts of quantum computing, safeguarding long-life communications infrastructure is becoming increasingly vital, particularly in sectors where reliability and operational continuity are essential.

The project successfully integrated Arqit’s quantum-safe encryption technology into Es’hailSat’s live satellite environment at the 25.5/26° East hotspot, utilizing the existing operational infrastructure of Es’hailSat’s Tier-4 certified Teleport facility in Doha. The demonstration proved that quantum-safe cryptographic protection can be implemented across current satellite-connected networks without negatively affecting existing systems, services, or operational performance.

This initiative validates a feasible approach for introducing quantum-safe protection into established satellite environments that support government, enterprise, maritime, energy, and critical infrastructure communications. Es’hailSat supplied the operational satellite environment utilizing the Es’hail-1 satellite, while AIEE spearheaded systems integration and interoperability testing across the ground and network infrastructure.

“Satellite infrastructure supports some of the world’s most operationally sensitive environments,” stated Andy Leaver, CEO of Arqit. “What’s important about this project is that it proves a practical path to strengthening quantum-safe cryptographic resilience without requiring operators to rebuild existing infrastructure. That operational reality matters especially in critical infrastructure environments, where disruption simply isn’t an option.”

Ali Al Kuwari, President & CEO of Es’hailSat, added: “Es’hailSat’s satellite networks are critical to Qatar’s national infrastructure, economic development and secure digital transformation across the Middle East and North Africa region. This collaboration reflects our commitment to exploring technologies that can strengthen long-term communications resilience while maintaining operational continuity for customers and stakeholders operating critical services.”

Adam St Paul, Chief Technology Officer at AIEE, noted: “This demonstration shows that organisations do not need to replace existing systems to achieve stronger security. By introducing quantum-safe protection into operational environments, satellite operators and critical infrastructure providers can ensure their communications remain resilient against the growing challenges posed by both state and non-state actors, while maintaining the continuity and reliability upon which their operations depend.”

The successful demonstration lays the groundwork for future quantum-safe satellite communications deployments, aiding secure enterprise connectivity, sovereign communications resilience, and the long-term protection of critical infrastructure.
