Military Quantum Communications

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 and entanglement-enabled encrypted channels — ensuring ultra-secure, interception-proof communications, on a resilient, rapid-deployment CubeSat architecture.

Capability

Secure quantum defence communications

A next-generation 3U CubeSat delivering ultra-secure, space-based quantum communications for defence and national security operations.

Beyond interception

Quantum Key Distribution

Phoenix demonstrates space-based QKD, enabling fundamentally secure communication channels resistant to eavesdropping.

Tamper-proof

Entanglement-Enabled Security

The mission explores entanglement-driven communication to create highly secure, tamper-proof data links for military use.

Rapidly deployed

Scalable Defence Networks

A resilient CubeSat platform enables scalable, fast-to-deploy quantum communication infrastructure for modern defence.

Payload
Quantum Optics

Entangled photons, miniaturised

Phoenix employs a compact source of entangled photons and quantum optics sensors.

This enables quantum key distribution for unbreakable encryption, secure satellite-to-satellite and satellite-to-ground links, and resilient communications in denied, degraded, or contested environments — fully miniaturised and optimised for CubeSat-class power budgets.

Sovereign
Quantum Capability

Securing the future of defence comms

Phoenix establishes the UK's independent, space-based quantum communications capability.

By deploying entanglement-enabled, encrypted channels, the mission ensures sensitive defence and intelligence data remain secure from interception — giving decision-makers confidence in communications integrity even in contested or denied environments.
