Europe and PQC

The European roadmap

The European Commission issued its PQC recommendation in April 2024. EU Member States, supported by the Commission, adopted a coordinated implementation roadmap in June 2025. It calls for Member States to begin transition by the end of 2026 and for high-risk use cases to transition as soon as possible, no later than the end of 2030.

These are roadmap milestones, not a claim that every organization has the same statutory algorithm deadline. Determine applicable national, sector, procurement, and contractual requirements for each workload.

Translate coordination into a local plan

• Assign a migration owner and maintain a cryptographic dependency inventory.
• Identify high-risk services and information with long confidentiality needs.
• Coordinate with suppliers and cross-border service partners.
• Choose interoperable protocol profiles and test both endpoints.
• Record exceptions, dependencies, and evidence supporting completion.

PQC and quantum communications

PQC uses mathematical algorithms on conventional systems. Quantum communication initiatives, including quantum key distribution, involve different infrastructure and assumptions. They should not be treated as interchangeable migration solutions.
