Why the Quantum Field Theory?
Quantum Mechanics II: Advanced Topicsuses more than a decade of research and the authors’ own teaching experience to expound on some of the more advanced topics and current research in quantum mechanics. A follow-up to the authors introductory book Quantum Mechanics I: The Fundamentals, this book begins with a chapter on quantum field theory, and goes on to present basic principles, key features, and applications. It outlines recent quantum technologies and phenomena, and introduces growing topics of interest in quantum mechanics. The authors describe promising applications that include ghost imaging, detection of weak amplitude objects, entangled two-photon microscopy, detection of small displacements, lithography, metrology, and teleportation of optical images. They also present worked-out examples and provide numerous problems at the end of each chapter.

"The second volume of this textbook contains many advanced topics of current research in quantum mechanics. The problems concerning the considered subject are included at the end of any chapter. The textbook is intended for graduate students and also as a reference book. Doubtless advantage of this tutorial is to have material on current research, such as supersymmetric quantum mechanics, coherent and squeezed states, Sagnac effect, quantum computers, quantum cryptography, and so on. A separate chapter is devoted to discussing some of the issues that are at the forefront of current research: quantum gravity, quantum Zeno effect, quantum teleportation, quantum games, quantum cloning, quantum diffusion, and quantum chaos."

"… excellent, up-to-date … can be used as either a two-to-three-semester graduate text or as a standalone reference book. Quantum Mechanics I: The Fundamentals covers the canonical basics and Quantum Mechanics II: Advanced Topics covers a range of modern developments from introductory quantum field theory through quantum information theory and other quantum technologies, such as quantum metrology and imaging, that are not discussed in other sources … I recommend this set highly."
