Post-Quantum Cryptography Timelines: When Will Organizations Migrate?

The article examines post-quantum cryptography migration timelines from governments, technology companies, financial institutions, infrastructure operators, and blockchain communities. Major organizations have set different transition targets, with regulatory deadlines extending to 2035 while several technology companies are targeting earlier migration milestones around 2029. The analysis finds that organizations broadly agree on starting post-quantum migration planning despite differences in estimates for when cryptographically relevant quantum computers may arrive. Every major organization has published a timeline. Governments, technology companies, financial institutions, critical infrastructure operators, and blockchain communities – all of the major players disagree on when a cryptographically relevant quantum computer will arrive, but none of them have published a “wait and see” position. As TQI’s Year of Quantum Security coverage has tracked, 2026 has become the year where that broad agreement on action became concrete – with deadlines, roadmaps, and product commitments replacing general awareness. This article maps what the major players have actually committed to, where the ranges cluster, and what the spread tells organizations still deciding how to prioritize their own migration. Regulatory deadlines form the bottom line. It’s important to note that they are the bare minimum expectations, not the…
