Phys. Rev. B 65, 081309(R) (2002) [4 pages]Intrinsic exciton-exciton coupling in GaN-based quantum dots: Application to solid-state quantum computing
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. © 2002 The American Physical Society URL:
