VIAVI Explains Quantum-Ready Networks

Viavi’s briefing cuts through quantum hype to explain how networks will become quantum‑ready, emphasizing that test and measurement is the governance layer that transforms experimental quantum cryptography into deployable services. The company outlines a hybrid security model that blends quantum key distribution (QKD), post‑quantum cryptography (PQC) and legacy classical mechanisms, noting that the overall link is only as strong as its weakest component. Key insights include the need to validate performance impacts of larger PQC keys, the physical constraints of QKD such as distance, key‑rate and photon loss, and the importance of crypto‑agility—designing networks that can switch algorithms as threats evolve. Viavi stresses end‑to‑end testing that spans fiber, transport, and application layers, allowing engineers to see how a physical‑layer disturbance cascades through key generation and algorithmic performance. Representative remarks underscore the urgency: “the threat is five to six years away, so harvest‑now‑decrypt‑later drives immediate inventory reviews,” and “the weakest point on the link determines security.” The discussion also touches on the emerging synergy between quantum computing and AI, suggesting both fields will accelerate each other’s development. For enterprises, the implication is clear: quantum‑ready testing must become a continuous, operational function, not a one‑off lab exercise. Companies that embed hybrid validation now will safeguard performance, control costs, and avoid costly retrofits when quantum‑capable adversaries emerge.
