Quantum Dots for Quantum Information Technologies Theory of semiconductor quantum dots single dot lasing superradiance and two photon emission Theory of phonon dressed light matter interactions and resonance fluorescence in quantum dot cavity systems Resonantly excited quantum dots: superior non classical light sources for quantum information Generation of time bin entangled photon pairs and hyper entanglement Generation of polarization entangled photon pairs QDs in nanowires The physics of large quantum dots in photonic nanostructures Enhancing photon photon and spin photon interaction with cavity QED Nanophotonic interface for quantum dot spin qubits Cavity QED effects and transform limited photons Deterministic single photon sources based on quantum dot microlenses Photonic integrated circuits with quantum dots Ultrafast manipulation of spins in quantum dots Coherent control of dark excitons in quantum dots Hybrid quantum dot atomic systems Generation of quantum dot spin entanglement. This book highlights the most recent developments in quantum dot spin physics and the generation of deterministic superior non classical light states with quantum dots. In particular it addresses single quantum dot spin manipulation spin photon entanglement and the generation of single photon and entangled photon pair states with nearly ideal properties. The role of semiconductor microcavities nanophotonic interfaces as well as quantum photonic integrated circuits is emphasized. The latest theoretical and experimental studies of phonon dressed light matter interaction single dot lasing and resonance fluorescence in QD cavity systems are also provided. The book is written by the leading experts in the field.
