Question to the Department for Science, Innovation & Technology:

To ask the Secretary of State for Science, Innovation and Technology, what steps he is taking to help tackle the threat posed by quantum computing to cybersecurity infrastructure.

The government recognises the cyber threats posed by quantum computing. The NCSC recently issued new guidance to help organisations prepare for and protect against threats posed by future developments in quantum computing [https://www.ncsc.gov.uk/guidance/pqc-migration-timelines]. The guidance is focused on migrating to post-quantum cryptography to mitigate the potential future quantum threat to encryption services, and identifying and mitigating cyber risks during the migration.

The Department for Science, Innovation and Technology and NCSC have also commissioned external research to understand industry barriers and incentives to migrate to post-quantum cryptography. This will be used to inform future policy interventions to drive the transition.

The government continues to monitor developments in quantum computing and uptake of post-quantum cryptography, including working with other countries to keep UK citizens and organisations secure. The government continues to assess wider cyber risks from critical and emerging technologies on an ongoing basis.
