Summary
In December 2025, the NCSC and Vodafone, with the National Cyber Advisory Board, hosted the first UK government and industry workshop focused on post-quantum cryptography (PQC) migration. The event brought together security leaders and those responsible for PQC in their organisations from across industry, academia and government. This energising and inspiring day reinforced a simple but critical point; no organisation can navigate the shift to PQC alone. So this blog aims to bring insights from the day to a wider audience. As the NCSC has explained, in the future, a sufficiently powerful quantum computer will be able to break the public key cryptography that protects our networks and systems today.
