The book "Single Quantum Dots" provides a comprehensive overview of the latest developments in the field of semiconductor quantum dots. It brings together contributions from leading researchers who focus on the optical and electronic properties of individual quantum dots. These properties are of great importance for the development of devices that operate with single electrons and photons. The work addresses topics such as quantum dots in electric and magnetic fields, quantum optics in cavities, the generation of non-classical light sources, and the coherent optical control of excitons. Additionally, various growth techniques and potential applications of quantum dots, such as quantum dot lasers and ultrafast amplifiers, as well as innovative concepts like quantum computing, are discussed.
