Abstract

II–VI quantum dots are used to control and to manipulate single charge and spin excitations in semiconductors. Two‐photon excitation enables us to generate an entangled state and to control the emission cascade of the exciton‐biexciton system. On charged quantum dots, we demonstrate direct optical manipulation of the resident electron spin. The spin life‐times are significantly larger than 10 µs in low magnetic field.

## Abstract We have studied the electronic structure, exciton states and optical spectra of spherical semiconductor quantum dot quantum wells (QDQW's) by means of a symmetry‐adapted tight‐binding (TB) method. We have investigated two classes of QDQW's: CdS/HgS/CdS, based on a CdS core which acts as
