Over the coming years, there will be a large-scale migration of IT and operational technology systems to use post-quantum cryptography (PQC), as a mitigation to threats to cryptography from future large-scale quantum computers.  This has implications for industry, government and regulated sectors; building robust migration plans is critical to managing this transition.   In this session, we will give an overview of the challenge, and then a panel will explore how organisations can prepare for migration to PQC.
