Our research aims to develop and exploit key enabling quantum technologies for emerging applications in quantum information science. This includes photon sources, interfaces and detectors, for work spanning applied and fundamental aspects of quantum communication, from QKD prototypes to teleportation, in the lab and in real world networks. Underlying this we have activities in quantum metrology to better characterise these emerging quantum technologies and applications as well as exploiting them for sensing and imaging, for example, in biophotonics.
