Quantum Communication Systems

Technician working at illuminated server racks in a data centre — Fiber optic cables in a server room form the terrestrial backbone that quantum satellite key distribution makes unbreakably secure.

Quantum Key Distribution via Satellite Link

1
QKD Satellite
Emits entangled photon pairs downward
2
Optical Downlink
Photons received at ground telescope stations
3
Key Reconciliation
Quantum keys extracted, errors corrected locally
4
Secure End Users
Encrypted comms immune to interception

A quantum satellite distributes entangled photon keys to ground stations, enabling provably secure encrypted communication between end users.
