Proponents refer to the emerging quantum internet (Quaint) as being “highly anticipated”, and while large-scale/commercial quantum networks do not exist at this juncture, they are expected to enjoy some embryonic deployment by the end of the current decade. Quantum computing, particularly in conjunction with a high level of interconnectivity facilitated by quantum connectivity, can facilitate a host of new, previously unattainable applications—these include blind quantum computation, (information) teleporting, clock synchronization, quantum key distribution, secure access to remote quantum computers, superdense coding, secure identification, distributed sensors, and other scientific and commercial applications. This book aims at a basic introduction for practitioners to emerging quantum communications foundations and applications—it is not targeted to researchers but telecommunications professionals. Basic quantum mechanics principles are discussed, within a minimalistic, mostly selfcontained mathematical framework. A handful of other text sources emerged in the recent past, but our goal is to make the science accessible to the “person of ordinary skill in the art”—a typical telecom practitioner— and to provide an up-to-date description of the discipline. Naturally, a reader should not expect to get a fully inclusive learning of the field, especially the underlying quantum mechanics, from a single text. For the interested reader, this book can serve as a point of departure, coupled with a set of other references that focus on specific aspects of the quantum computing and quantum mechanics discipline. After an introductory overview chapter, Chapter 2 covers basic concepts in quantum physics by describing some mathematics needed for the discussion, while trying to keep the machinery to a minimum. Chapter 3 continues the discussion by addressing some more advanced mathematics, but with an eye for clarity. Chapter 4 covers basic concepts in quantum physics by describing some physical technologies, while also keeping the science to a sufficient minimum. Chapter 5 provides an overview of quantum computers, being that these nodes constitute the endpoints to be supported by the quantum internet over the horizon. Chapter 6 focuses on quantum communications, including logical architectures and the Quaint. Next, in Chapter 7, we endeavor to provide an accessible discussion of quantum-based security. Chapter 8 offers information on software tools that can be employed to develop networked quantum applications. The glossaries not only define key terms in each of the chapters, but also elaborate on various concepts introduced in the respective chapters and should be read through as part of the instructive process. This text is not intended as review of current research activities or a complete tutorial on this matter. Furthermore, the authors have not developed any of the science or mathematics of quantum mechanics. Therefore, the background material included in a number of chapters originates from the industry at large, with liberal acknowledgements to the sources of the information. The goal of this text is to synthetize the background material and highlight the applicability to the newly emerging field of quantum communication and quantum internet, in an approachable manner, so that managers and other non-practitioners can get a basic understanding of the discipline as subsetted and applied to the field of remote connectivity and networking.
