Abstract: The theoretical background of communication over quantum channels is based on the fundamental results of quantum information theory. The actual state of quantum information theory reflects our current knowledge of the quantum world, and it also determines the success of quantum communication protocols and techniques. This chapter overviews the possible attacks against the quantum key distribution protocols, and discusses the quantum bit commitment protocol, quantum fingerprinting, and quantum public key cryptography. The classical capacity of a quantum channel can be measured in different settings, depending on whether the input contains tensor product or entangled quantum states, and the output is measured by single or by joint measurement settings. The physical implementations of quantum communications networks will be based mainly on optical communications. The theoretical quantum protocols are just idealizations of the practical systems, without the imperfections caused by the environment. Controlled Vocabulary Terms communication channels; information theory; Optical fiber communication; public key cryptography; quantum communication; telecommunication networks
