Our research studies interactions between light and nanoscale systems such as single atoms, electron spins and nanomechanical structures. Using nanofabrication methods to engineer the optical properties of these systems, it is possible to dramatically enhance light-matter coupling, opening the door to experiments which use light to delicately measure and transmit information describing the dynamics of nanoscale quantum systems.
Recent research results involve coupling single quantum emitters, or "artificial atoms," to optical nanocavities. These quantum emitters are formed by nitrogen vacancy (NV) color centers in diamond. In addition to possessing atom-like optical properties, diamond NV centers have electron and nuclear spins which can be controlled optically, and whose quantum state is useful for storing information and sensitively probing magnetic fields. This research has applications in the emerging field of quantum information processing, in developing low power optical devices, and creating sensitive and compact environmental sensors.
We are fortunate to have labs at both the University of Calgary and the NRC National Institute for Nanotechnology (NINT) located at the University of Alberta. In Calgary, we work within the Institute for Quantum Science and Technology (IQST) alongside other leading quantum optics research groups. At NINT, we interact with a diverse set of researchers whose expertise spans all areas of nanotechnology, and we have access to some of the most advanced nanofabrication tools in Canada.
