Arqit, Es’hailSat and AIEE Demonstrate Quantum-Safe Satellite Communications

Insider BriefPRESS RELEASE – 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.“Satellite infrastructure supports some of the world’s most operationally sensitive environments,” said 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.”Mr.

Ali Al Kuwari, President & CEO of Es’hailSat, said: “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 servicesAdam St Paul, Chief Technology Officer, AIEE, said: “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 establishes a foundation for future quantum-safe satellite communications deployment, supporting secure enterprise connectivity, sovereign communications resilience, and the long-term protection of critical infrastructure.TopicsShare Get the latest research, company news, and market intelligence every week. MENTIONED IN THE ARTICLEArqit specializes in quantum-safe security. The company protects data and networks from threats posed by quantum computing. Its software-defined encryption platforms and cryptographic solutions help organizations in telecoms, government, and defense secure their communications and infrastructure. Encryption Intelligence is Arqit's cryptographic discovery, inventory and posture management solution. It maps where cryptography lives across an organization's estate. It identifies quantum-vulnerable protocols and generates prioritized post-quantum migration plans, backed by continuous discovery. Arqit also offers NetworkSecure and its Symmetric Key Agreement (SKA) platform. These deliver on-demand encryption keys to harden VPNs, critical links and cloud workloads. Together, the solutions address the risks of quantum-enabled attacks and evolving PQC compliance requirements. They are scalable, standards-based, and compatible with existing infrastructure, with no rip-and-replace required.The Association of Energy and Electrical Engineers (AIEE) is a non profit group with its history dating back to the late 19th century. It was initially established in 1884 and played a significant role in the development of electrical engineering as a profession.More in Research
