In today's communication networks, the widespread use of optical fiber and passive optical elements allows using quantum cryptography in the current standard optical network infrastructure. Recently, the telecommunication requires large amount of data transfered via satellites, but an interesting way of dealing with this problem might be using quantum communications.

Produktbeschreibung
In today's communication networks, the widespread use of optical fiber and passive optical elements allows using quantum cryptography in the current standard optical network infrastructure. Recently, the telecommunication requires large amount of data transfered via satellites, but an interesting way of dealing with this problem might be using quantum communications. In the book three topics are addressed: sending classical and quantum information through a noisy quantum channel; limits of the quantum algorithms possibly used in space communications; information spreading in mobile ad hoc communication systems. It is possible with the power of quantum computing to create a communication system in which quantum bits are used but there is no need for quantum redundancy. To achieve this, redundancy-free and pilot quantum based error coding methods are discussed. In second topic, different quantum protocols are analyzed for the possible use in space communication. The third topic is information spreading in quantum and classical network in the viewpoint of quantum communications and space communications.
