The UK Quantum Communications Hub is celebrating a decade of groundbreaking research, having made significant strides in developing unhackable networks for secure data transmission. Led by the University of York, the hub has created a quantum-secured network connecting Bristol, Cambridge, and London, leveraging the principle that particles of light can transmit data along optical cables in a fragile state, making it impossible to intercept or manipulate sensitive information.
Director Professor Tim Spiller notes that their work is now poised for commercialization and widespread adoption. Notable achievements include successfully testing a fibre-optic cable for quantum communications under the Irish Sea, as well as projects on space quantum communications, miniaturized secure transfer devices, and scalable energy-efficient solutions.
Key partners include Toshiba Europe, BT, and the National Physical Laboratory, with support from the Engineering and Physical Sciences Research Council through the UK National Quantum Technologies Programme.
Celebrating a Decade of Advancements in Quantum Communications
The UK Quantum Communications Hub is marking a significant milestone – 10 years of groundbreaking research and development in quantum communications. This achievement is a testament to the power of collaboration, as researchers from various institutions have come together to advance our understanding of how digital information can be shared safely and securely.
One key factor contributing to the Hub’s success has been its partnerships with industry leaders and academic institutions. The University of York, which leads the Hub, has worked closely with experts from Bristol and Cambridge to develop working testbeds connected via London. These partnerships have enabled the creation of an unhackable UK quantum-secured network, a significant step forward in ensuring the security of digital information.
The principles underlying quantum communications are rooted in the fragile state of particles of light, which can transmit data along optical cables. This fragility means that any attempt to manipulate or steal private data in transit will cause the particles to collapse, making it detectable and secure. The Hub’s research has focused on harnessing this phenomenon to develop practical applications for secure communication.
Clear Vision and Commercial Potential
The Hub’s Director, Professor Tim Spiller, has emphasized the significance of the milestone, stating that the Hub has achieved all its technology development objectives over the past decade against a clear vision. This achievement paves the way for commercial value and widespread use of quantum-secured communications networks. The potential applications are vast, with opportunities to grow initial quantum-secured communications networks using standard fibre optic cabling to support both commercial applications and the next steps towards a quantum internet.
Recent research breakthroughs have demonstrated the feasibility of using fibre-optic cables to enable quantum communications underwater, with scientists successfully testing a fibre-optic cable under the Irish Sea between the Republic of Ireland and England. This achievement marks the longest stretch of fibre-optic cable ever used for quantum communications underwater and the first time a quantum link has been tested between Ireland and the UK.
Exploring the Frontiers of Quantum Science
The Hub’s research has also delved into other areas, including space quantum communications, where experts have created secure communications via satellite over all distances. Another project has focused on developing a miniaturized, low-cost prototype that could open up a market for secure transfer using mobile devices. Additionally, researchers have worked on enabling scalable, energy-efficient quantum secure solutions for mass-market deployment.
Since its creation in 2014, the Hub has led projects to develop quantum science into communications technologies with commercial uses. This work has been instrumental in advancing our understanding of matter and energy at the fundamental level, with significant implications for the development of secure communication systems.
Industry Partnerships and Collaborations
The success of the Hub can be attributed, in part, to its strong industry partnerships. Researchers have collaborated with over 30 industry partners, including Toshiba Europe and BT, as well as academic institutions from across the country. The National Physical Laboratory and RAL Space are among the organizations that have worked closely with the Hub.
Andrew Lord, BT Senior Manager, Optics and Quantum Research, has emphasized the significance of these partnerships, stating that they could not have achieved their current position without the close interaction with the Quantum Communications Hub and the associated support from Innovate UK. The access to world-class research has unlocked the power of quantum for them, and they are excited to see how they can now start to commercialize it.
