Quantum sciences
Quantum science exploits the unique principles of quantum mechanics to revolutionise computing, communications and sensing. Whether developing quantum algorithms for advanced computations or creating quantum-based cryptographic systems, quantum technologies hold the promise to create radically new products and applications, transforming different industrial sectors, from cyber-security to chemical diagnostics, to healthcare. Partnerships with global research organisations and industry leaders ensure that this innovative research translates into practical, real-world solutions across various sectors.
Our Institute of Photonics and Quantum Sciences (IPaQS) is at the heart of a focused quantum research ecosystem, which also includes the Institutes for Signals, Sensors and Systems (ISSS) and Biological Chemistry, Biophysics and Bioengineering (IB3), working to tackle some of the world’s most pressing challenges. Heriot-Watt has major strengths in quantum networking, quantum-enhanced imaging and sensing, and quantum materials. Since 2014, this area has been awarded research funding of over £100M, awarded a range of prestigious Fellowships, and trained more than 50 PhDs.
Our research in this area is diverse, with many different applications. We are leading efforts to build secure long distance quantum communication networks, including satellite-based links and the development of quantum memories and quantum repeaters. We develop and utilise quantum sensors as small as one single electron and deploy them to characterise next generation nano-devices, and to detect small quantities of biomolecules associated to disease. We create novel imaging schemes based on single photons, which enable superior image resolution and the tracking of fast-moving objects. Furthermore, we study novel quantum materials with novel and exotic properties, to create devices with new functionalities.
We are part of four of the five new quantum Hubs, established by the UKRI Engineering and Physical Sciences Research Council (EPSRC) to ensure the UK benefits from the potential of quantum technologies. Heriot-Watt leads the “Integrated Quantum Networks Hub” (IQN) and is involved in the UK Hub for Quantum Enabled Position Navigation and Timing (QEPNT), The UK Quantum Technology Research Hub in Sensing, Imaging and Timing (QuSIT) and the UK Quantum Biomedical Sensing Research Hub (Q-BIOMED). Industry collaboration is key to these hubs, leveraging cash and in-kind contributions from partners worth more than £54 million.
In IQN alone, over £20 million in industrial support will help translate our quantum innovations into new products and services. IQN’s teams of physicists will also work in partnership with over 40 non-academic collaborators, ranging from startups to multinational corporations, alongside organisations like the National Cyber Security Centre and Scottish Enterprise.
By bringing together experts in quantum technologies and photonics, IPaQS fosters a collaborative environment where innovative solutions can be developed. This interdisciplinary approach is strengthened through external partnerships, ensuring the research not only advances scientific understanding but also delivers real-world impact across multiple sectors.
