&
Abstract
At low enough temperatures, quantum dots in semiconductors can have sharp optical transitions, similar to those of atoms. In recent years there has been intense interest in demonstrating various coherent optical control techniques in these 'artificial atoms' for applications in quantum communication, quantum computation and nonlinear optics at low light levels.
