Arqit Quantum Inc. (NASDAQ:ARQQ, ARQQW))), a global leader in quantum-safe encryption, Es’hailSat - the Qatar Satellite Company - a world-class satellite operator and service provider with coverage spanning the MENA region - and Advanced International Electronic Equipment Company (AIEE), a specialist systems integrator for secure communications infrastructure, today announced the successful demonstration of quantum-safe security across operational satellite communications infrastructure.

The collaboration demonstrates a practical way for satellite operators and critical infrastructure providers to strengthen communications resilience in the face of emerging quantum threats, without interrupting live operations.

As governments and infrastructure operators prepare for the cybersecurity implications of quantum computing, protecting long-life communications infrastructure is becoming increasingly important. This is particularly relevant in sectors where reliability and operational continuity are critical.

The collaboration integrated Arqit’s quantum-safe encryption technology within Es’hailSat’s live satellite environment at 25.5/26° East hotspot, using existing operational infrastructure of Es’hailSat’s Tier-4 certified Teleport facility in Doha. The demonstration showed how quantum-safe cryptographic protection can be introduced across existing satellite-connected networks with no adverse effect to existing systems, services or operational performance.

The project validates a practical and feasible route for introducing quantum-safe protection into existing satellite environments supporting government, enterprise, maritime, energy and critical infrastructure communications.

Es’hailSat provided the operational satellite environment using Es’hail-1 satellite for the demonstration, while AIEE led systems integration and interoperability testing across the ground and network infrastructure.
