Post-Quantum Cryptography Timelines: When Will Organizations Migrate?

Major organizations are setting varying targets for migrating to post-quantum cryptography, with some technology companies aiming to complete the transition as early as 2029, while regulatory deadlines extend to 2035. Despite these differences, there is broad agreement on the need to start planning for post-quantum migration, driven by the narrowing timeline for cryptographic migration due to quantum developments¹. The migration timelines are being driven by the potential for quantum computers to break current encryption standards, making it essential for organizations to adopt post-quantum cryptography to maintain security. Governments, financial institutions, and infrastructure operators are among the entities that need to migrate to post-quantum cryptography, with the urgency of planning increasing as quantum computing capabilities advance. This migration is critical for organizations to ensure the long-term security of their data and systems, so practitioners must prioritize post-quantum cryptography planning to stay ahead of the potential quantum threat.
