Abstract
This report evaluates the threats quantum computing poses to current cryptographic systems and explores post-quantum cryptography (PQC) solutions. It assesses global research initiatives, standardisation activities led by NIST and ETSI, and early implementations designed to introduce quantum-resistant algorithms. The study maps the European landscape of PQC readiness and recommends a phased migration strategy for critical infrastructure, government systems, and private sector deployments across the EU.
