Question to the Department for Science, Innovation & Technology:

To ask the Secretary of State for Science, Innovation and Technology, what progress she has made in developing photonic computing.

DSIT are funding an Innovation and Knowledge Centre led by the University of Southampton’s world leading silicon photonics research foundry, Cornerstone. This centre is focused on translating silicon photonics technologies from research to industry, including photonic integrated circuits that are essential for optical computing.

In parallel, the UK’s National Quantum Computing Mission aims to build scalable quantum computers. We have already announced over £1bn of funding for the quantum technologies sector – which includes over £500m specifically around the development of quantum computing of which photonic approaches are an integral part. Details of key milestones and funding programmes under this investment will be published soon.
