Abstract
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.

Notes
- 1.
Here we follow the formalism \(\mathrm{c} \rightarrow \mathrm{c}\), \(\mathrm{c} \rightarrow \mathrm{q}\), etc., used by Holevo and Giovannetti in a recent paper [4].

The rate of NASA Voyager 2 at Jupiter in 1979 mission was of 115.2 kbit/s. This was achieved acting on several factors: increasing the transmitting and the receiving antenna diameters and also increasing the transmitter power (see Problem 4.4).
