Quantum Satellite Communications
Tier 2 · $1.8B (2025) · +28% CAGR
Quantum satellite communications uses the principles of quantum mechanics to distribute encryption keys via satellite, providing theoretically unbreakable security. QKD (quantum key distribution) from satellites enables secure key exchange over distances impractical for terrestrial fiber. The sector is driven by growing concerns about quantum computers breaking conventional encryption and the need for quantum-safe communications infrastructure.
