Quantum Technology

Earl Russell Excerpts

Tuesday 24th February 2026 Lords Chamber

[Lord Vallance of Balham (Lab)]

My noble friend asks an important question. There is no doubt that UK quantum companies look pretty attractive at the moment. We have a good idea of where those companies are, what their skills are and what is going on across the quantum space, but I believe there is a need to have all the levers in place to make sure that these companies stay in the UK. Yes, that is about funding, but also about regulation, procurement and giving the signals that can leverage the investment that these companies will need, as many of them are getting up to very significant valuations.

We will take the Lib Dems then come to the Conservative Benches.

[Earl Russell (LD)]

My Lords, quantum technology clearly has profound implications for our future national security, including for the secure communications on which we all rely and for potential future threats to cryptography. How are the Government working to ensure the alignment of the national quantum strategy with our cyber and national security strategies? What assessment have the Government made of the UK’s sovereign capability in key parts of the quantum supply chain?

[Lord Vallance of Balham (Lab)]

There are two important parts to that question. First, it is necessary to make sure that all existing data go through into post-quantum cryptography—in other words, into things that cannot be broken by quantum computers. That process is being led by the National Cyber Security Centre, which is working with businesses and trying to get them into place to have that ready, but it is not a short-term project. It will take quite a long time to get all that done. Secondly, the race is on to make sure that we are at the very forefront of getting a working, scaled quantum computer, because that is what will give us an advantage in all these areas. We work very closely with the security agencies across all this.
