Technologies that harness quantum effects have huge potential. We are currently witnessing rapid development in this area: research has already led to quantum technologies with applications ranging from precision time keeping to high accuracy inertial measurements and tests of fundamental theories. In my group, we are working on the further development of these technologies with the aim of utilising the quantum nature of ultra-cold atomic matter. Our projects include work with superconducting atom chips, Bose-Einstein condensates, miniaturized optical systems for quantum information processing and building a compact and transportable atom interferometer for the precise determination of local gravity.
