The UK Quantum Programme Risks Getting Lost In The Noise Of The DSIT Reshuffle

Within the first weeks of Andy Burnham’s premiership, the government he now leads abolished the Department for Science, Innovation and Technology. The written statement announcing the change on 21 July runs to about a thousand words, and it carefully accounts for where everything is going, with artificial intelligence sent to one place, digital policy to another, and the teams and portfolios reassigned line by line. Nowhere in it does the word quantum appear. For a technology to which the British government had committed up to £2 billion only four months earlier, that silence is worth pausing on.

Of that £2 billion, a full £1 billion is earmarked to buy quantum computers through a procurement competition called ProQure. Applications closed in May, and the first contracts are due to be announced in October. The department that designed the competition, however, no longer exists, which means the earliest and most concrete test of the new arrangements will fall due within weeks of those arrangements being created.

There is a piece of physics buried in that timing, and it is worth understanding because it describes the risk with unusual precision. A quantum bit, or qubit, is almost never destroyed by anything dramatic. Instead it decoheres, which is to say that the surrounding environmental noise gradually swamps the fragile signal it carries until the information is simply lost, with nothing along the way that resembles an attack. The qubit does not so much fail as fade, until it can no longer be told apart from the noise around it.

The UK quantum programme now faces a version of the same process. Almost nobody expects the money to be cancelled outright, and anyone forecasting a press release that withdraws it will most likely be proved wrong. The more realistic danger is quieter and much harder to see, namely that a national commitment built up over more than a decade slowly becomes one modest line item inside a vast department whose week is dominated by steel, tariffs and trade negotiations. What follows is an attempt to separate the parts of the UK quantum programme that are structurally protected from the parts that are not.

What the government actually did

The decision was Andy Burnham’s. As the Guardian first reported in the days before the reshuffle was confirmed, the new prime minister had asked officials to draw up plans to abolish DSIT as part of a wider Whitehall shake-up, and the written statement of 21 July duly carried it through. The old department was then broken into three.

Science, innovation and the industrial strategy went to the Department for Business and Trade, which was duly renamed the Department for Business, Innovation, Science and Trade under Jonathan Reynolds. Digital policy moved to an enlarged culture department, while artificial intelligence and the AI Security Institute were pulled into the Cabinet Office at the very centre of government.

The way the ministerial jobs were distributed reveals the government’s priorities more plainly than any strategy document could. Kanishka Narayan was appointed Minister of State for Artificial Intelligence on 20 July, with a seat in Cabinet, which is a first for the field in Britain. The same statement went on to create an AI Taskforce inside the new Cabinet arrangement and backed it with a dedicated prime ministerial adviser.

Quantum, by contrast, has had a national strategy, its own office and a ten-year funding commitment since 2023, yet it emerged from the same reshuffle with a new letterhead and little else. No minister owns the brief by name. None of this proves that AI was treated too generously, because the case for coordinating AI from the centre is a genuinely strong one. What it does demonstrate is that the government knows exactly how to give a technology real institutional weight when it chooses to.

The technology industry objected almost at once. Julian David of techUK and Dom Hallas of the Startup Coalition jointly called the break-up the “wrong change at the wrong time”, while Matt Clifford, who had advised two prime ministers on AI, described it bluntly as “a big mistake”. Sir Paul Nurse, president of the Royal Society, warned in the same spirit that science “is in no way a junior partner”.

Why this is a risk, not a cancellation

Two days of silence in the immediate aftermath of a major reshuffle does not, on its own, prove very much. New departments routinely take weeks to publish an organisational chart and months to settle into a working rhythm, so this is not a claim that quantum has quietly been dropped. It is a narrower and more urgent point, which is that the decisions likely to determine the UK quantum programme’s standing are being taken right now, out of sight, by officials assembling a department from scratch.

That is precisely why the timing matters so much. The sector has only a short window in which to make its case before the new structures harden into something permanent. We set out the broader scenarios facing the industry when Andy Burnham’s plans first leaked, and the task here is the next one along, which is to say plainly what is protected and what is exposed.

What is safe

Physicists protect a fragile quantum state by isolating it from the world behind shielding, vacuum and extreme cold. Several parts of the UK quantum programme enjoy a comparable kind of insulation, and they are worth identifying before the harder argument begins. What they have in common is that they do not sit inside the abolished department, so a change of name above them does not reach them quickly or easily.

The National Quantum Computing Centre is the clearest example, since it sits within UK Research and Innovation rather than within any single department. It was established with £93 million channelled through the research councils, and its purpose-built home at Harwell opened in 2024. Its budget does not travel down a departmental line, and neither does the money that reaches British quantum companies through the research councils and Innovate UK, which together means that a renamed department cannot easily interrupt any of it.

The National Physical Laboratory is cushioned in a similar way, because it is a company with a single shareholder, so that shareholding simply transfers to the new department without any real disruption. The National Quantum Strategy, with its £2.5 billion commitment spread across ten years, remains official policy, as do the five national missions built on top of it. Unpicking a flagship strategy in the first week of a new department would hand the government a damaging headline that it has every reason to avoid.

What is exposed

One part of the programme, however, had no such wall around it. The Office for Quantum was itself a creation of the National Quantum Strategy, and it sat inside DSIT, which is exactly why it is now the element most at risk. Its value was never really its budget or its headcount, but rather the direct line it provided to the National Science and Technology Council, the Cabinet-level body that the prime minister chairs.

Most industries would trade a great deal of grant funding for a connection of that kind. Should the office now be folded into a general innovation team within the new department, quantum would lose no money on day one, but it would lose its seat in the room where priorities are set and budgets are carved up. No quantity of published strategy can compensate for an empty chair once the real spending decisions begin.

The second exposure concerns the board that actually runs the UK quantum programme. It brings the research councils, Innovate UK, the NQCC, the National Physical Laboratory, GCHQ, the Ministry of Defence and, until 21 July, DSIT around a single table, and that unusual mixture of research funders and security agencies is a large part of why the UK quantum programme works at all. The departmental seat has not been abolished, but who now occupies it, and at what level of seniority, is an open and consequential question.

Dr Alicia Greated, chief executive of the Campaign for Science and Engineering, framed the broader worry well when she said it was vital that Jonathan Reynolds “champions the whole R&D system” and that “curiosity-led and discovery research must continue to be protected within a larger department”. Quantum sits at the sharp end of that worry, because it is expensive, slow to mature, and unlikely to deliver its full return until long after the next election.

How a programme fades away

Programmes of this kind rarely die by announcement, and far more often they simply fade. A funding round slips by a quarter, and then by another. A director’s post stays vacant through a hiring freeze, a planned update to the strategy never quite reaches a minister’s desk, and an official who once spent half the week on quantum finds that it has shrunk to a tenth. Each of these has an innocent explanation on its own, yet taken together they are precisely how the UK quantum programme can lose its way without anyone ever deciding that it should.

The threat, in other words, is not hostility but the ordinary background noise of a very large department. Steel, tariffs, business rates and industrial disputes generate urgent correspondence and parliamentary questions in a way that a technology still years away from widespread use simply does not. A minister confronted by a trade crisis on a Monday morning is not being negligent when quantum drifts down the agenda, and that is exactly the problem, because the signal does not need an enemy in order to be lost.

Reorganisation also consumes the one resource that is always in short supply, which is senior attention. The Institute for Government estimates the upfront cost of a new department or mid-sized merger at around £15 million, with a further £19 million or so in lost productivity, and its research shows the disruption stretching well beyond the first year. Those are months in which almost nobody is free to fight for a comparatively small programme, so the quantum brief has to survive them without a champion, at the very moment the ProQure contracts fall due.

What other countries are doing

Britain’s decision looks stranger still when it is set beside what its closest allies were doing in the same few weeks. On 22 June the White House issued an executive order on quantum that gave the president’s science adviser 180 days to refresh the national strategy and the federal personnel office 90 days to devise a plan for recruiting and retaining quantum specialists, special rates of pay included. It then distributed the commercial work across the Departments of War, Commerce and Energy, the National Science Foundation, NASA and the National Security Agency.

The direction of travel there is unmistakable, because the order pulls quantum towards the president’s own office. In the same summer, London pushed it in the opposite direction, down into a business department. Nor is this simply one American choice weighed against one British one, since when the OECD reviewed national quantum strategies in December 2025 it found that France, Japan and the United States all run their programmes from the top of government. Britain has just moved the other way.

Investors follow these signals closely, since reading them is a large part of their job, and a great deal of real money is already committed. Oxford Quantum Circuits raised £260 million in June, one of the largest private quantum rounds ever closed by a European company, announced during the prime minister’s own London Tech Week speech, with £100 million of it coming from the British Business Bank. Public and private capital are now so tightly braided together in these firms that a government signal reaches the balance sheet long before it reaches the laboratory.

A warning from the industry

The industry’s own version of the argument is blunter. Sebastian Weidt, chief executive of Universal Quantum, said in a statement that “departmental structures come and go”, and that what actually matters to companies building long-term technology is “certainty, pace and a government that treats innovation as central to growth”. His concern is commercial rather than sentimental. “Deep tech firms decide where to scale based on the signals governments send,” he said, adding that he hoped the new prime minister would keep “emerging technology at the core of his plans for the economy”.

Weidt is careful not to argue against the AI appointment itself. He called a Cabinet minister for AI “encouraging” before drawing the obvious inference from it. “The logic applies well beyond AI,” he said. “Quantum computing will shape everything from drug discovery to national security, and the race for it is at a far earlier and more decisive stage.” His preferred remedy is not a second minister but a broader brief, since a remit “covering the full breadth of emerging technology”, he suggested, would give the UK “a stronger hand than one drawn around a single field”.

Universal Quantum is a pointed source for that warning. The company builds modular trapped-ion machines designed to be manufactured in conventional silicon factories, having spun out of the University of Sussex in 2018 under Weidt and Professor Winfried Hensinger, and it holds a €67 million contract with the German Aerospace Center to build quantum computers in Hamburg. That is British university research being scaled up on a German government contract, which lends unusual weight to Weidt’s closing point. “Britain’s research heritage is the bedrock of its next generation of companies,” he said. “That pipeline from lab to economy is a national asset, and it deserves a strong voice at the heart of government.”

Why the rescue may come from Cheltenham

There is, however, a genuine counterweight, and it sits in Cheltenham rather than in Whitehall. GCHQ and the Ministry of Defence hold their seats on the programme board because quantum touches national security at almost every level, from post-quantum cryptography to quantum sensing for defence. Those interests were not created by a department, and they will not disappear simply because one has been abolished.

The National Cyber Security Centre has already committed to a firm timetable. Organisations are expected to complete their planning by 2028, to carry out the highest-priority upgrades between 2028 and 2031, and to finish migrating to post-quantum cryptography by 2035. Those dates function as a baseline for operators of essential services rather than as a law binding everyone, but they nonetheless create obligations that no reshuffle can pause.

The same statement also moved the Investment Security Unit, which screens acquisitions on national security grounds, out of the Cabinet Office and into the new business department. The department therefore inherits real security machinery rather than none, and for a sector that has watched Cambridge Quantum, Rahko and Oxford Ionics pass into foreign ownership, having that unit in the same building may matter quite as much as the loss of the Office for Quantum.

The likeliest conclusion is that the sector’s most effective ally over the coming year will be the security establishment rather than the science one. Security arguments tend to survive contact with a business department in a way that appeals to research excellence often do not, and if protection does arrive it will almost certainly be framed in terms of sovereign capability and supply-chain resilience. The firms best able to speak that language will find doors opening that stay firmly shut to everyone else.

What to watch before the autumn

The signals worth watching are small and undramatic, which is exactly why they tend to be missed. The first of them is October, because if the ProQure contracts are announced on schedule the machinery will have survived the move intact. If they slip without a clear explanation, that will be the earliest solid indication of what the reshuffle has actually cost.

After that, the organisational chart is the thing to study, and the question is whether the Office for Quantum reappears as a named unit with a named director or is quietly absorbed into some broader innovation team. It is worth watching, too, for a minister who takes the quantum brief by name, and for how long that takes, as well as for any trimming of the National Physical Laboratory’s budget or the missions in the spending review. Above all, it is worth watching whether quantum keeps a standing place on the agenda of the National Science and Technology Council, which is the truest test of whether that line to the centre has survived.

The bottom line

The government’s own argument, set out in the statement, is that placing science alongside business and trade will convert research into jobs faster than a standalone science department ever could. That is a serious proposition rather than a cynical one. A well-run department could, in principle, offer British quantum firms better routes into public contracts and export markets than they have enjoyed so far, and Reynolds now holds both the science brief and the trade levers with which to do it.

Even so, the physics is worth one final glance. A quantum computer does not stay stable by being left undisturbed in a quiet room, because in that contest the noise always wins in the end. It stays stable through error correction, which means measuring constantly, catching drift early and correcting it again and again. Stability, in other words, is never something you set once and then forget, since it has to be actively maintained or it slips away.

Britain spent more than a decade, and a considerable sum of public money, building the UK quantum programme, and the companies that have emerged from it are a real asset rather than a prospectus. That programme has now lost the department created to hold it, four months after being promised £2 billion and with its first contracts due in October, and ministers have so far said nothing at all about any of it. The burden of proof has shifted firmly onto them, and the first instalment falls due in the autumn.
