The Global PQC Implementation Playbook for sovereign countries PQC Readiness provides a structured, twelve-month roadmap that guides governments and enterprises through seven phases of PQC adoption. The Playbook outlines each phase—from governance planning and cryptographic inventory to full-scale deployment and continuous readiness auditing—defining objectives, timelines, metrics, and alignment with Singapore's QRI and CSA 2025 framework. By following this work plan, sovereign countries member states and organizations can achieve measurable, standards-based quantum resilience through coordinated governance, proven technology integration, and sustained capability development.
