We undertake research in quantum physics and technology, exploiting micro- and nano-scale optical devices. Our mission is to test fundamental physics, and develop applications in metrology, communication, and biomedical imaging and diagnosis. Much of our research is based on optical architectures integrated on silicon chips, and is compatible with present-day fibre optical systems. These architectures provide a test bed for a wide range of quantum phenomena including entanglement and non-locality, quantum enhanced measurements and microscopy, quantum optomechanics, and the physics of two-dimensional superfluids. The robustness and scalability of our systems offer potential for the investigation of macroscopic quantum systems and phenomena. Visit our research page for more details on the research activities of our group.
