Quantum engineering ? the design and fabrication of quantum coherent structures ? has emerged as a field in physics with important potential applications. This book provides a self-contained presentation of the theoretical methods and experimental results in quantum engineering. The book covers topics such as the quantum theory of electric circuits, theoretical methods of quantum optics in application to solid state circuits, the quantum theory of noise, decoherence and measurements, Landauer formalism for quantum transport, the physics of weak superconductivity and the physics of two-dimensional electron gas in semiconductor heterostructures. The theory is complemented by up-to-date experimental data to help put it into context. Aimed at graduate students in physics, the book will enable readers to start their own research and apply the theoretical methods and results to their current experimental situation.

? A unified exposition of methods used in the theoretical description of artificial quantum coherent structures ? Provides the tools for theorists to begin their own research, whilst also giving experimentalists an overview of the methods and results ? Advanced theoretical methods, as Green's functions techniques or path integrals, are avoided
