Abstract
Post-quantum cryptography is no longer an abstract problem. It’s a technology transformation that touches every layer of critical infrastructure, from policy to procurement, systems to supply chains. In this episode, Dr Jeremy Bradley, Principal Technical Director at the UK’s NCSC and lead author of the government’s official PQC timeline guidance, breaks down how the UK is approaching this monumental shift.
Jeremy explains why the NCSC focused on organisational readiness and available technology rather than waiting for a cryptographically relevant quantum computer (CRQC). He unpacks how government and industry can work together without formal policy mandates, the importance of sector-wide movement, and what it takes to make your supply chain quantum-safe.
What You’ll Learn:
- Why PQC migration is best treated as a technology change programme, not a cryptographic fix
- The UK’s phased migration roadmap and why 2035 is a realistic end-date
- How advisory bodies like NCSC shape national direction without enforcing policy
- What legacy infrastructure, vendor roadmaps, and sector alignment have in common
- How to drive internal buy-in using the language of risk, not quantum timelines
- Why collaboration, transparency, and shared learning are critical in high-stakes sectors
Jeremy is Principal Technical Director for Cryptography and High Threat Technologies at the UK’s National Cyber Security Centre (NCSC). He leads the team behind the newly released Timelines for Migration to Post-Quantum Cryptography guidance. At NCSC, Jeremy oversees cryptographic assurance for the UK’s sensitive systems, advises across government and regulated sectors, and drives strategy for secure implementations. His work spans technical standards, inter-agency cooperation, and future-focused guidance to help the UK become quantum-safe.
