Introduction to Part II: Quantum Communications

  • Gianfranco CariolaroEmail author
Part of the Signals and Communication Technology book series (SCT)


In this chapter the foundations of Telecommunications Systems are outlined and the differences between Classical and Quantum Communications are explained. Also, the leading concepts of the so-called digital revolution are outlined to justify the choice of dealing only with digital communications in this book. The second part of the chapter deals with the foundations of optical classical communications, which is the necessary prologue to optical quantum communications developed in the subsequent chapters. The mathematical framework for optical classical communications is given by Poisson processes, which are introduced in the final part and applied to classical photodetection.
