Playing a prominent role in communications, quantum science and laser physics, quantum nonlinear optics is an increasingly important field. This book presents a self-contained treatment of field quantization and covers topics such as the canonical formalism for fields, phase-space representations and the encompassing problem of quantization of electrodynamics in linear and nonlinear media. Starting with a summary of classical nonlinear optics, it then explains in detail the calculation techniques for quantum nonlinear optical systems and their applications, quantum and classical noise sources in optical fibers and applications of nonlinear optics to quantum information science. Supplemented by end-of-chapter exercises and detailed examples of calculation techniques in different systems, this book is a valuable resource for graduate students and researchers in nonlinear optics, condensed matter physics, quantum information and atomic physics. A solid foundation in quantum mechanics and classical electrodynamics is assumed, but no prior knowledge of nonlinear optics is required.
Abstract: Quantum-cryptography represents a revolutionary advancement in the field of secure correspondence, leveraging the principles of quantum-mechanics to ensure unprecedented levels of security. This review paper provides a comprehensive exploration of both the foundational principles and advanced techniques underpinning quantum cryptographic systems. We begin by examining the theoretical foundations, including quantum key distribution (QKD) protocols such as BB84 and E91, and the critical role of entanglement and superposition in these processes. The paper then delves into the latest advancements and techniques in the field, including device-independent QKD, quantum cryptographic networks, and post-quantum cryptographic methods designed to be resilient against quantum computer attacks. Additionally, we discuss practical implementation challenges and the current state of experimental quantum cryptography. By synthesizing recent research findings and technological developments, this review aims to provide a thorough comprehension of the current environment and future directions of quantum cryptography, highlighting its potential to revolutionize secure communications in the quantum era.
The field of quantum optics has witnessed significant theoretical and experimental developments in recent years. This book provides an in-depth and wide-ranging introduction to the subject, emphasising throughout the basic principles and their applications. The book begins by developing the basic tools of quantum optics, and goes on to show the application of these tools in a variety of quantum optical systems, including lasing without inversion, squeezed states and atom optics.

For many contemporary physics experiments, the use of microwave and optical resonators has become a powerful tool for enhancement in detection sensitivities, nonlinear interactions, and quantum dynamics. Most often, the term cavity is used to describe such electromagnetic resonators. This term has been taken over from microwave technology, where resonators really look like closed cavities, whereas optical resonators traditionally have an open kind of setup. That difference in geometry is related to the fact that optical resonators are usually very large compared with the optical wavelength, whereas microwave cavities are often not much longer than a wavelength. As discussed in the course of this book, microwave and optical cavities allow one to extend the interaction length between matter and field, to build up the optical power, to impose a well-defined mode structure on the electromagnetic field, to implement extreme nonlinear optics, and to study manifestly quantum mechanical behavior associated with the modified vacuum structure and/or the large field associated with a single photon confined to a small volume [100].
