University of Exeter news in 5-Year Quantum Research Program
The University of Exeter is leading a five-year multinational collaboration to revolutionize quantum sensing technologies. The £1.5 million UKRI-funded initiative aims to bring quantum sensors out of the lab and into the real world by overcoming their accuracy-limiting “noise”. The Japan-UK collaboration is anticipated to transform GPS-free navigation and early-stage medical diagnosis.
Challenge: Overcoming Quantum “Noise”
Most modern sensors, including accelerometers and light sensors in smartphones, are based on classical physics. Quantum sensors work at the atom, electron, and photon level, making them a huge advance. Thus, they can detect signals too weak for ordinary instruments.
Decoherence is the main obstacle to this method. Quantum states are sensitive, and external factors like temperature variations, vibrations, and electromagnetic interference can cause “noise” that disrupts the sensor and hides the measured data.
Fragility: Small environmental influences can hide signals.
This “noise” is unpredictable and unwanted, making precision harder to maintain.
The Solution: The Exeter-led team is developing smarter control algorithms and noise-resistant technologies to make these sensors work in “noisy” environments.
According to University of Exeter Professor Janet Anders, making these sensors faster, more accurate, and more robust to external impacts would enable measurements and technical advancements that were previously unattainable.
Revolutionizing Healthcare: Seeing the Invisible
This study will impact medical imaging immediately and profoundly. Current diagnostic tools like MRI and CT scanners are important yet cumbersome, expensive, and frequently lack resolution for early disease detection.
The project aims to create wearable or portable brain imaging equipment using noise-resistant quantum computing. These sensors could detect brain neuronal magnetic fields with unprecedented clarity.
Medical advances may include:
Early Diagnosis: Identifying the onset of neurodegenerative disorders such as Alzheimer’s or Parkinson’s years before physical symptoms show.
Cancer Treatment Tracking: Monitoring cancer cell metabolism in real time to see if a treatment works.
High-resolution, real-time brain mapping improves understanding.
Beyond GPS: Navigation's Future
The medical center and cooperation promise to transform international transportation and security via satellite-free navigation. GPS satellites are used for modern navigation, however they can fail in remote areas, underwater, and in towering buildings. Since GPS signals are faint, unscrupulous people can jam them.
Exeter researchers are developing quantum gyroscopes and accelerometers. These devices are precise enough to calculate a vehicle's position without a satellite link using its own motion. This “GPS-denied” navigation could change several businesses.
Self-Driving Cars: Ensuring safe navigation in low-signal areas.
Aviation and Shipping: Providing a secure backup to keep planes and ships on course if global satellite networks are attacked.
In areas where satellite signals cannot reach, deep-sea exploration allows accurate location.

Strategic International “Brain Trust”
The project advances Japan-UK scientific relations. The UK consortium, coordinated by Exeter, includes Nottingham and King's College London researchers. The University of Tokyo, Okinawa Institute of Science and Technology, and Waseda University form a Japanese cooperation similar to this.
This relationship is about building a professional network, not just sharing data. A key five-year strategy component is:
Extended Exchange Visits: Japanese junior researchers will visit UK universities, while UK researchers will visit Japanese labs.
Sharing Expertise: Each partner brings unique technological skills to achieve the project's lofty goals.
Training the Next Generation: The project trains a new generation of quantum professionals to keep both nations at the top of the “quantum race”.
Dr. Lucia Hackermueller of Nottingham University underlined the significance of global collaboration to enable photon storage and sophisticated navigation systems.
How Frontier Science Will Reach 2031
The Living Systems Institute and Physics Department of Exeter will host the project. The purpose is to build physical tools, but most of the work involves fundamental physics.
Dr. Mark Mitchison of King's College London said the group will investigate new sensing systems that use quantum particles' complex motion to boost sensitivity. The team hopes to combine theoretical physics and practical technology by mixing modern data processing with cutting-edge atomic and photon sensors.
The team hopes to conduct proof-of-principle trials by 2031, the completion of the five-year study. These tests will show how noise-resistant sensors can be utilized in brain imaging, opening the way for mass-market implementation.
This project establishes Exeter as a global leader in frontier science research that improves and replaces technology. Sub-atomic perception may be the most valuable tool of the 21st century in an age of data and precision.
