Well, for Matthew Stone NextGen Nan Quantum Division, the focus will be in two directions. Firstly, efforts to manipulate materials, and create new, lower bandgap materials will increase. Band gap reduction is important for establishing quantum properties because doping the material with charge carriers increases the conductivity. Finally, the role of crystal size in observing superfluorescence should also be a focus.
