This paper describes a novel model for the dynamics of the dipole coherence in two-level quantum dots (QDs) interacting with localized photons. The model is based on the fact that the coupling on a nanometer scale between QDs via optical near fields represented by localized photons is much stronger than that via propagating far fields. The model predicts that an intriguing phenomenon such as a collective dipole oscillation occurs if the initial quantum states are locally manipulated. The origin of this kind of collective behaviour is discussed in view of Dicke's superradiance.
