Quantum Information Technology

White Rose Quantum Information Network

The members of the White Rose Quantum Information Network have been collaborating, co-supervising PhD students, and running regular joint meetings since 2005. The latest series of meetings are being run under the auspices of the White Rose supported studentship network "Optimising Quantum Processes and Quantum Devices for future Digital Economy Applications", which currently supports PhD students at Leeds, Sheffield and York under this research theme.

Optimising Quantum Processes and Quantum Devices for future Digital Economy Applications

Home page at the White Rose Consortium

It is now widely known that quantum information (QI) offers huge potential for future technologies and services to support the Digital Economy. Examples include quantum computers that could outperform any conventional computers, quantum communication protocols that guarantee unbreakable security and quantum sensors that offer unprecedented sensitivity.

The aim of this project is to optimise quantum devices and quantum protocols for future quantum technologies and services. The planned research will be carried out in three overlapping and complementary theoretical research areas. We are very fortunate within the White Rose collaboration to have internationally recognised QI activities at all three network nodes. The two researchers in Sheffield (Whittaker, Kok) belong to one of the world-leading research groups for quantum control of nanoscale systems. The network further includes the Head of the Leeds QI group (Spiller), recognised for his quantum technology expertise and industrial experience, a leading expert on quantum optics (Beige) and two recognised experts on quantum processes and protocols at York (Busch, Weigert).

The three groups in this proposal have been strategically selected to have the necessary diversity and range of skills to address the following question at both fundamental and practical levels: How to best turn theoretical QI devices and concepts into new technologies and services? Achieving this goal requires a close collaboration with experimental groups (at Sheffield and Leeds). The device focus of two of the proposed projects links directly to these experimental activities. The QI process and protocol research will be based on the expertise at all three network nodes, with focus provided from the industrial experience of Spiller at Hewlett-Packard in Bristol.
