This book highlights the physical processes of quantum mechanics, such as quantum interference, entanglement, and quantum teleportation, within the topic of quantum information and quantum computing.

Quantal and Classical Coherence and Correlation begins with exploring the general mathematical and physical concepts of coherence and correlation and provides a comparative discussion of classical and quantum coherence and correlation. In this context, the author explains the principles of quantum information, and the discussion then moves to material coherence and optical coherence and their control. He then discusses the differences between classical and quantal information techniques. The book closes with a discussion on the application probabilities of quantum technologies by examining the present and future applications of coherence.

This book is intended for upper?level undergraduate and graduate physics and engineering students who are studying nonlinear optics, light–matter interaction, and quantum information; and industrial professionals who are involved in electronics and photonics. It will also be of interest to engineers who are involved in quantum information and quantum networks.
