Quantum-Safe Readiness: Operators Prepare for Q-Day

Speakers at the Barcelona discussion warned that “Q-Day” — the point when quantum computers can break today’s encryption — is likely four to eight years away, and urged organizations to act now because adversaries are already harvesting data to decrypt later. They recommended deploying post-quantum cryptography and hybrid approaches (including quantum key distribution) while acknowledging distance and deployment limits, and emphasized AI-driven, end-to-end defenses to close weak links. Practical steps include comprehensive inventories of data and systems, prioritizing long-lived data for immediate protection, and building crypto agility to switch algorithms as standards evolve. Identity and certificate lifecycle management, plus carrier and service-provider roles in protecting transport, were highlighted as critical operational priorities.
