Question to the Department for Science, Innovation & Technology:

To ask the Secretary of State for Science, Innovation and Technology, with reference to page 41 of the Information Commissioner’s Office report on Quantum Technologies published on 9 October 2024, what assessment he has made of the potential implications for his policies of the conclusions on post-quantum security.

The government recognises the need to act to both unlock the opportunities of quantum computing and also address the potential risks of this technology.

DSIT works closely with the National Cyber Security Centre to identify the mitigations that are required against the cryptography risks posed by quantum computers.

Following the publication of Post Quantum Cryptography (PQC) standards this summer, NCSC has published details of how it will help organisations plan their migration to PQC. This complements existing cyber security guidance for data security.

NCSC will release further communications over the coming months and continue supporting regulators, such as the Information Commissioner’s Office, to manage these risks within their remits.
