A handheld eye scanner and a way to find rail faults where GPS fails
What happened
On 13 October 2026, the government announced a package of funding for quantum technology companies in the UK. The total comes to £78 million, split three ways. The largest slice is £50 million for quantum sensing projects, awarded through a UK Research and Innovation competition covering sensing and what is called positioning, navigation and timing. The aim is to help companies move from early testing to products that can actually be sold and used. A further £20 million goes to building UK quantum communication networks and the supply chain behind them, including lasers and photonic chips. The last £8 million expands an apprenticeship scheme called QuEST, with a target of 150 engineering apprentices supporting the quantum workforce by 2030. The announcement came from the Department for Business, Innovation, Science and Trade, UK Research and Innovation, and the Science, Innovation and Investment Minister, Chris McDonald MP. Several of the funded projects were named. MoniRail, in the West Midlands, is working on highly accurate positioning to find faults in railway track and signalling in places where GPS does not work. Siloton, based in London and Bristol, is building a handheld eye scanner intended to bring advanced eye diagnostics beyond specialist hospitals. ColdQuanta UK, in Oxfordshire, is making a compact mobile radio antenna that can pinpoint signals, with uses in defence, airport resilience and search and rescue. Aegiq, in Sheffield, makes quantum communication components. Others listed include QLM Technology in Wales, working on a camera that detects greenhouse gases in infrastructure; Quantum Fabrix in Oxford, on next-generation satellite clocks; and Cerca Magnetics in Nottingham, on a wearable brain scanner used before epilepsy surgery.
Why this matters
Quantum technology has spent two decades being described as promising. The interesting thing about this list is how ordinary the problems are. Finding a faulty bit of railway signalling is not glamorous. It is, however, one of the main reasons trains run late. If an engineer can locate a fault precisely in a tunnel or a cutting where satellite signals do not reach, the repair happens faster and fewer people stand on a cold platform. The eye scanner is the one most likely to touch readers directly. Advanced eye imaging currently tends to live in hospital eye departments. A handheld version could in principle be used somewhere closer to home - which is exactly the kind of change that shortens a waiting list, because it moves the first look at a problem out of the bottleneck. The wearable brain scanner for epilepsy sits in the same category. Scans before epilepsy surgery are specialised and uncomfortable, particularly for children. A wearable version is a quality-of-life change as much as a technical one. And the apprenticeships matter in a way that is easy to skip past. Advanced manufacturing in the UK has a long history of good inventions and not enough people trained to build them at scale. £8 million is small next to £50 million, but 150 apprentices is a workforce, not a press release. The minister's framing was blunt: "Quantum has long been an exciting technology, but now real world applications are within our grasp."
What the evidence actually says
This is funding for development, not proof that any of these devices work in the NHS or on the railways today. That distinction deserves stating plainly, because announcements like this are often read as if the products already exist. What has actually happened is that companies have won competitive grants to move from early testing towards real-world products. Some will succeed. Some will not. That is how this stage of development works, and it is why the money is spread across a portfolio rather than put behind one device. The medical devices in particular face a further step that the announcement does not cover. A handheld eye scanner or a wearable brain scanner intended for clinical use in the UK has to satisfy the medical device rules and be assessed by the regulator before it can be used on patients routinely. Winning a research grant is not the same as being approved, and it is not a timeline for arriving at your local clinic. The wider context is real, though. The government says the funding supports a goal of making the UK a world leader in quantum sensing by 2030, backed by up to £2 billion committed earlier in 2026. Professor Charlotte Deane, who leads UKRI's quantum work, added a point that explains some of the official enthusiasm: "These technologies also matter for our national security." Several of the funded projects - precise navigation when satellites fail, secure communications, signal location - are dual-use by nature. So: credible institutions, real money, named companies with specific problems. No finished products yet.
Practical advice
There is nothing here to do today as a patient or a passenger. But there are a few reasonable ways to read news like this. Treat "could cut waiting lists" as a direction, not a date. A funded prototype is typically years from routine NHS use, and some never get there. If you are currently waiting for an eye appointment, this announcement does not change your place in the queue. If you have an eye condition, keep your existing appointments. Diabetic eye screening, glaucoma checks and routine optometrist visits are the things that actually protect sight now. Future scanners are no reason to skip a present appointment. If you or your child is on an epilepsy pathway, ask your specialist team what pre-surgical assessment currently involves locally. That is a better source than national funding news. If you work in engineering or are choosing a career path, the apprenticeship route is the concrete opportunity in this announcement. QuEST is explicitly being expanded, and the target runs to 2030. And if you run a small technology business, the relevant detail is the route, not the headline. These awards came through UK Research and Innovation competitions, which publish their calls openly. The £20 million networking competition and the sensing competition are the kind of thing worth watching for next time round.
What to know
The government announced £78 million for UK quantum technology on 13 October 2026: £50 million for quantum sensing, £20 million for quantum communication networks and supply chains, and £8 million to expand the QuEST apprenticeship programme towards 150 apprentices by 2030. Named projects include MoniRail's precise positioning for finding railway faults where GPS fails, Siloton's handheld eye scanner, ColdQuanta UK's compact mobile antenna, Aegiq's photonic components, and Cerca Magnetics' wearable brain scanner for epilepsy assessment. These are development grants, not approved products. The medical devices would still need to clear the UK's medical device regulations before routine clinical use. Keep your current eye and epilepsy appointments; nothing announced here changes them.
