The book provides an overview of the most advanced quantum informational geometric techniques, which can help quantum communication theorists analyze quantum channels, such as security or additivity properties. Each section addresses an area of major research of quantum information theory and quantum communication networks. The authors present the fundamental theoretical results of quantum information theory, while also presenting the details of advanced quantum ccommunication protocols with clear mathematical and information theoretical background. This book bridges the gap between quantum...

"Navigare necesse est!" - If one compares wired and wireless/mobile communications several differences can berecognized in such fields as security, power consumption, mediumaccess, channel behavioretc. However, themost differently handled resource is bandwidth. In case ofwired networkslink capacity can overcome almost any limitations by deploying optical fibres. Spectral efficiency is one of the mostsignificant key parameters of every mobile system. Spectrally efficient wireless solutionsare fairly complex, they consist of techniques applied in physical and data link layers.Call Admission...

Quantum computers will revolutionize the way telecommunications networks function.

Quantum computing holds the promise of solving problems that would be intractable with conventional computers by implementing principles from quantum physics in the development of computer hardware, software and communications equipment.

Quantum-assisted computing will be the first step towards full quantum systems, and will cause immense disruption of our traditional networks. The world's biggest manufacturers are investing large amounts of resources to develop crucial quantum-assisted...
