Abstract

Summary form only given. Semiconductor quantum dots are attracting much interest as a candidate to implement the quantum information processing and the quantum computation. In order to examine the possibility of the quantum state manipulation, we study the excitonic Rabi flopping and a new type of quantum interference phenomena in semiconductor quantum dots. One of the most striking manifestation of the quantum coherence is the Rabi flopping. The observation of the excitonic Rabi splitting in an InGaAs quantum dot was reported recently. Under the strong excitation of an excited exciton state in a single quantum dot, the luminescence from the exciton ground state shows a doublet splitting. This splitting can be interpreted in the dressed exciton picture. Namely, under the strong and resonant excitation of a particular exciton state, the ground state of the system splits into two levels. Then the transition from the exciton ground state to the split ground state results in the doublet structure of the emission spectrum.
