Quantum Optics for Engineers provides a transparent and methodical introduction to quantum optics via the Dirac's bra–ket notation with an emphasis on practical applications and basic aspects of quantum mechanics such as Heisenberg's uncertainty principle and Schrodinger's equation. Self-contained and using mainly first-year calculus and algebra tools, the book: Illustrates the interferometric quantum origin of fundamental optical principles such as diffraction, refraction, and reflection Provides a transparent introduction, via Dirac's notation, to the probability amplitude of quantum entanglement Explains applications of the probability amplitude of quantum entanglement to optical communications, quantum cryptography, quantum teleportation, and quantum computing. Quantum Optics for Engineers is succinct, transparent, and practical, revealing the intriguing world of quantum entanglement via many practical examples. Ample illustrations are used throughout its presentation and the theory is presented in a methodical, detailed approach.

Despite initial set backs in the 1980s, the prospect for large scale integration of optical devices with high spatial-density and low energy consumption for information applications has grown steadily in the past decade. At the same time these advances have been made towards classical information processing with integrated optics, largely in an engineering context, a broad physics community has been pursuing quantum information processing platforms, with a heavy emphasis on optics-based networks. But despite these similarities, the two communities have exchanged models and techniques to a very limited degree. The aim of this thesis is to provide examples of the advantages of an engineering perspective to quantum information systems and quantum models to systems of interest in optical engineering, in both theory and experiment. I present various observations of ultra-low energy optical switching in a cavity quantum electrodynamical (cQED) system containing a single emitter. Although such devices are of interest to the engineering community, the dominant, classical optical models used in the field are incompatible with several photon, ultra-low energy devices like these that evince a discrete Hilbert space and are perturbed by quantum fluctuations. And in complement to this, I also propose a nanophotonic/cQED approach to building a self-correcting quantum memory, simply "powered" by cw laser beams and motivated by the conviction that for quantum engineering to be a viable paradigm, quantum devices will have to control themselves. Intuitive in its operation, this network represents a coherent feedback network in which error correction occurs entirely "on-chip, " without measurement, and is modeled using a flexible formalism that suggests a quantum generalization of electrical circuit theory.

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.
