Semiconductor quantum dots (QDs) are regarded as potential candidates for the implementation of solid state quantum computation. The basic ingredient for the realization of a quantum computer are Rabi oscillations - a sinusoidal time evolution of the population difference in a two-level system that is observed under strong resonant optical excitation (Stievater et al., 2001). In this contribution...
The spin relaxation within the radiative doublet of the exciton ground state in InAs/GaAs quantum dots is studied via ultrafast spectral hole burning spectroscopy. A biexcitonic resonance emerges due to relaxation of the exciton spin.
The electron relaxation dynamics in self-assembled InAs/GaAs quantum dots is investigated by tuning femtosecond mid-infrared pulses into resonance with intraband transitions and measuring the absorption as a function of time-delay after an interband pump pulse
