In our group we are researching the new materials and protocols needed for quantum communication, quantum computation and quantum sensing. The systems we use are rare earth ion crystals as they are a particularly promising candidates for building quantum information devices due to their excellent quantum coherence properties. This is crucial requirement to avoid the loss of quantum information through interactions with the local environment.
In our research we combine fundamental knowledge of the materials with the development of new quantum information protocols and device fabrication capabilities. This unique skillset has enabled us to achieve several key milestones in the field of quantum information processing, for example:
These recent breakthroughs have placed us in an exciting position to build a long-range quantum communication network, allowing the transmission of provably secure information through the use of quantum encryption. We are working towards this goal as part of the Centre for Quantum Computation and Communication Technology.
Our research program is broadly divided into four research streams.
Developing the protocols necessary to implement practical quantum networks
Developing the capability to integrate components for scalable quantum devices
