History

07/22/2026

The story is now anchored by a specific transatlantic implementation result: Colt and Ciena disclosed an 800Gbps quantum-safe transmission over 6,900 kilometers, while the Japan side is framed more clearly as an AI data-center demonstration. The added detail shifts the emphasis from general proof-of-concept claims to concrete technical validation, though still not commercial deployment.
