The University of Bristol is participating in two projects funded by Innovate UK as part of a £12 million initiative to advance quantum internet technology. These projects support the UK’s goal of establishing a leading quantum network by 2035. The first project, PAQNet, led by Alter Technologies UK, seeks to develop cost-effective photonic integrated circuits for scalable quantum networks, addressing Quantum Key Distribution (QKD) security challenges.
The second project, QUDITS2, led by Vector Photonics, explores using qudits for more efficient data storage and processing. Additionally, five other funded projects involve companies supported by Bristol’s Quantum Technology Enterprise Centre (QTEC), underscoring the university’s pivotal role in advancing the UK’s quantum capabilities.
University Of Bristol Leads Two Innovate UK Funded Projects
The University of Bristol is leading two Innovate UK-funded projects to advance quantum network technology. The first project, PAQNet, focuses on developing cost-effective and scalable photonic integrated circuits (PICs) for quantum networks. This initiative addresses key challenges in scaling Quantum Key Distribution (QKD) networks, essential for secure data transmission. By reducing deployment complexity and improving reliability for large-scale infrastructure, PAQNet aims to enhance the practicality of QKD systems.
The second project, QUDITS2, explores qudits—quantum particles capable of existing in more than two states—as a potential alternative to traditional qubits. Led by Vector Photonics, with Dr. Edmund Harbord heading the University of Bristol’s contribution, QUDITS2 investigates how qudits can improve data storage and processing efficiency within quantum networks. By leveraging UK photonics technologies, the project seeks to demonstrate the scalability and practicality of qudit-based systems, potentially reducing resource requirements for quantum communication.
Both projects strategically focus on advancing quantum networking technology through collaborative research. PAQNet addresses limitations in current QKD systems, while QUDITS2 explores higher efficiency in information transfer using qudits. These initiatives contribute to the development of robust and accessible quantum communication infrastructure, with applications in secure data transmission and advanced computing systems.
