This introductory chapter begins with the history of Quantum Mechanics, which has proudly been there for more than a hundred years, and certainly represents one of the most successful scientific theories of all history. At a macroscopic level, the phenomena foreseen by Quantum Mechanics are not appreciable, and only by observing them on an atomic or subatomic scale do they appear in full evidence. The chapter then goes through the revolutionary concepts of this discipline, eventually describing the recent developments in Quantum Communications and Quantum Information. The second part of the chapter deals with the organization of the book, which consists of three parts: (I) Fundamentals, (II) Quantum Communications Systems, and (III) Quantum Information.
