My research area sits at the intersection of the foundations of quantum theory, and quantum information theory. In particular, I am interested in basic questions about quantum mechanics, in particular the strange way in which particles that have previously interacted behave, and how this can be harnessed for applications in quantum information.
Quantum theory allows particles to be have a properties called entanglement, which means that they become entwined, or correlated, in a way which has no classical analogue. If particles which are entangled in one place are later sent far away, this entanglement persists, and when actions are performed on one particle, the other particles are influenced in ways which defy any classical explanation. This leads to startling effects, such as quantum teleportation, or the ability to distribute secret keys between distant parties which nobody else can find out.
My research aim is to better understand quantum entanglement, and in particular the ways in which this strange quantum effects manifests itself in numerous ‘nonlocal’ ways, and the potential uses for this in quantum information theory.
Although the focus of my work is primarily theoretical, it is evident that there is a lot of interest in future quantum technologies, which are now being invested in heavily, and my hope is that my theoretical insights will be relevant for these future technologies, in whatever shape they eventually take.
