In this Rapid Communication we propose to use GaN-based quantum dots as building blocks for solid-state quantum-computing devices. The existence of a, strong. built-in electric field induced by the spontaneous polarization and by the piezoelectricity is exploited to generate entangled few-exciton states in coupled quantum dots without resorting to external fields. More specifically, we shall show, how the built-in field induces intrinsic exciton-exciton coupling, which can be used to realize basic quantum information processing;on a sub-picosecond time scale.
