Military Quantum Communications Mission

Phoenix QuantumSat establishes a new frontier in defence communications by deploying a compact quantum optics payload in low Earth orbit. The mission demonstrates space-based quantum key distribution (QKD) and entanglement-enabled encrypted channels, ensuring ultra-secure, interception-proof communications for military operations. By combining quantum technology with resilient CubeSat architecture, Phoenix QuantumSat provides a scalable, rapid-deployment capability for secure defence networks.

Enabling Sovereign Defence Capability

At Infinity Space, our mission is to deliver actionable, secure, and sovereign communications from orbit. Phoenix QuantumSat enables, Quantum-encrypted links for mission-critical communications, Secure, low-latency data transfer in contested space environments and Rapid integration into national and allied defence networks. This platform transforms quantum optics from a research experiment into a fully operational, mission-ready defence capability.

Secure and Resilient Communications Architecture

The satellite’s communications subsystem delivers encrypted data transmission through a high-reliability UHF link. Advanced error-correction protocols ensure data integrity under challenging orbital conditions. Phoenix QuantumSat integrates seamlessly with sovereign ground stations and allied secure networks, maintaining mission assurance and protecting national security interests.

Phoenix QuantumSat integrates quantum optics sensors that measure entanglement and photon coherence in orbit. These sensors enable: Real-time verification of secure quantum channels, Rapid establishment of encrypted links between satellites and ground nodes and Continuous monitoring of link integrity for mission assurance. By combining quantum optics with high-precision attitude control and orbital stability, Phoenix QuantumSat ensures reliable, secure communication for defence applications.

Sovereign Quantum Capability – Securing the Future of Defence Communications

Phoenix QuantumSat establishes the UK’s independent, space-based quantum communications capability. By deploying entanglement-enabled, encrypted channels, the mission ensures that sensitive defence and intelligence data remain secure from interception. This sovereign capability provides decision-makers with confidence in the integrity of communications, even in contested or denied environments, protecting national security interests at the highest level.

Rapid, Resilient Communications in Contested Space

Modern military operations demand speed and reliability. Phoenix QuantumSat delivers ultra-secure, low-latency quantum communications directly from orbit, reducing dependency on vulnerable terrestrial networks. In rapidly evolving operational scenarios, this mission enables defence forces to maintain uninterrupted communications, enhancing responsiveness, situational awareness, and the ability to act decisively under pressure.

Pioneering the Next Generation of Defence Technology

Phoenix QuantumSat is more than a satellite it is a transformative step toward the future of military space technology. By integrating quantum optics, resilient CubeSat engineering, and secure communications, it lays the groundwork for advanced quantum-enabled constellations. This mission not only strengthens current operational capability but also establishes a foundation for future technologies that will define the next era of secure, space-based defence communications.

Securing the High Ground Quantum Advantage for Defence

Phoenix QuantumSat delivers a decisive edge in space-based communications, providing ultra-secure, sovereign quantum links that protect critical defence and intelligence operations. By combining cutting-edge quantum optics with resilient satellite engineering, the mission ensures uninterrupted, tamper-proof communications in contested environments, establishing the UK’s leadership in the next generation of military space technology.
