The UK's Big Bet on Quantum Computers

The UK government has ambitious plans for the quantum technology sector, committing £2.5 billion over ten years to support startups and university spin-outs. This significant investment is part of a National Quantum Strategy aimed at fostering the development of commercially viable quantum technology by 2033.

The government released a tranche of £45 million earlier this year to support this endeavor.

While the development of full-scale quantum computers is still in its early stages, with commercial applications expected in 5-10 years, some branches of the industry are already producing commercially available products.

Quantum Sensing: A Real-World Application

One such branch is quantum sensing, which leverages the principles of quantum mechanics to provide innovative solutions for various applications, including brain scanning, tumor detection, and underground mapping.

Quantum sensing technology utilizes the unique properties of quantum mechanics to create alternatives to conventional scanning and sensing methods.

These applications demonstrate the tangible benefits of quantum technology beyond the realm of theoretical research.

Cerca Magnetics: Brain Scanning with Quantum Technology

Cerca Magnetics, a joint venture between the University of Nottingham and Magnetic Shields, exemplifies the commercialization of quantum sensing. Founded in 2020, the company produces a wearable brain scanner that utilizes quantum technology.

This device, unlike traditional MRI machines, is lightweight, portable, and allows free movement, making it particularly suitable for working with children.

The technology behind Cerca Magnetics' scanner involves using lasers to manipulate the quantum state of atoms, transforming them into tiny magnets that detect magnetic activity in the brain.

The collected data can be used to conduct research into brain activities associated with various neurological conditions such as autism, epilepsy, and dementia.

Since its launch, Cerca Magnetics has sold its devices to researchers in the UK, Canada, the US, and Europe, including prestigious Ivy League universities and hospitals.

Delta.g: Mapping the Underground with Quantum Technology

Delta.g, a spin-out from the University of Birmingham launched in 2022, is another company harnessing the power of quantum sensing, but in a different domain: underground mapping.

Delta.g's system utilizes gravity gradient variations to identify underground structures that are otherwise difficult or impossible to detect.

The company's technology involves shooting light at two clouds of atoms, which are used together to take measurements while mitigating the effects of external vibrations.

Delta.g has secured significant funding from investors like SCVC, Quantum Exponential Group, and Maven Cognition, as well as grants from Innovate UK.

The company's goal is to create comprehensive "Google Maps" of the underground landscape, helping builders avoid hazards like gas pipes and dangerous structures.

Delta.g has already signed a prototype contract with the UK's Department of Transport and has collaborated with the Royal Navy and other partners.

Challenges and Opportunities

While quantum sensing is proving its worth in various applications, companies in this sector face unique challenges.

For Cerca Magnetics, a key challenge is securing regulatory approvals for its brain scanner to be used in clinical settings beyond research.

Delta.g focuses on expanding the applicability of its technology to a wider range of environments by shrinking the system and enhancing its portability.

Both companies emphasize that quantum sensing is not a technology of the future but a viable solution available today.

The National Quantum Technologies Programme: Supporting Quantum Startups

The National Quantum Technologies Programme plays a crucial role in supporting quantum startups in the UK. Through grants, competitions, and test bed facilities, the program provides vital resources for these emerging companies.

While the development of full-scale quantum computers is a long-term endeavor, the program recognizes the potential for quantum technology to make a real impact in the near future.
