Babcock and Arqit demonstrate quantum safe military communications network designed to protect battlefield data from future cyber threats

Babcock and Arqit have demonstrated a quantum-safe military communications network intended to protect battlefield data against future cryptographic attacks enabled by quantum computing, according to Defence Industry Europe. The demonstration used Arqit's QuantumCloud platform to generate and distribute encryption keys that remain secure against quantum decryption methods, a capability increasingly seen as essential for long-term protection of classified military communications. The trial establishes a proof-of-concept for integrating post-quantum cryptography into operational defence communications infrastructure.
