Download and read online ebook Spins in Optically Active Quantum Dots write by Oliver Gywat. This book was released on 2010-02-01. Spins in Optically Active Quantum Dots available in PDF, EPUB and Kindle. Filling a gap in the literature, this up-to-date introduction to the field provides an overview of current experimental techniques, basic theoretical concepts, and sample fabrication methods. Following an introduction, this monograph deals with optically active quantum dots and their integration into electro-optical devices, before looking at the theory of quantum confined states and quantum dots interacting with the radiation field. Final chapters cover spin-spin interaction in quantum dots as well as spin and charge states, showing how to use single spins for break-through quantum computation. A conclusion and outlook round off the volume. The result is a primer providing the essential basic knowledge necessary for young researchers entering the field, as well as semiconductor and theoretical physicists, PhD students in physics and material sciences, electrical engineers and materials scientists.

Towards Solid-State Quantum Repeaters available in PDF, EPUB and Kindle. Towards Solid-State Quantum Repeaters: Ultrafast, Coherent Optical Control and Spin-Photon Entanglement in Charged InAs Quantum Dots summarizes several state-of-the-art coherent spin manipulation experiments in III-V quantum dots. Both high-fidelity optical manipulation, decoherence due to nuclear spins and the spin coherence extraction are discussed, as is the generation of entanglement between a single spin qubit and a photonic qubit. The experimental results are analyzed and discussed in the context of future quantum technologies, such as quantum repeaters. Single spins in optically active semiconductor host materials have emerged as leading candidates for quantum information processing (QIP). The quantum nature of the spin allows for encoding of stationary, memory quantum bits (qubits), and the relatively weak interaction with the host material preserves the spin coherence. On the other hand, optically active host materials permit direct interfacing with light, which can be used for all-optical qubit manipulation, and for efficiently mapping matter qubits into photonic qubits that are suited for long-distance quantum communication.

The Coherent Nonlinear Optical Response and Control of Single Quantum Dots available in PDF, EPUB and Kindle. Work on this program is aimed at developing and understanding nano-optical structures with emphasis on developing quantum optical-based devices. Specific work focused on semiconductor quantum dots. The major achievements include the first demonstration of an all optically driven quantum NOT-gate based on using the exciton-Bloch vector as the qubit (Science 2003). We also demonstrated optical density matrix tomography on this system. Since the fast recombination time of quantum dot excitons may limit these systems for quantum information applications, we initiated experiments on negatively charged quantum dots (similar to ions) where for quantum information processing, the qubit would be the electron spin. The energy level structure in this system is a 3-level A-system, which is also of importance to novel coherent optical applications such as slow light and electromagnetic induced transparency. Our experiments in this system are just beginning, but we have successfully demonstrated optically induced coherence in this system, the unexpected effect of spontaneously generated spin coherence, and coherent optical control. A summary of our work leading up to this was published by invitation in Physics Today while the achievement of the quantum NOT-gate was reviewed in Photonics News.
