This book provides an overview of the latest R&D advancements in the field of ICT technologies inherent to a New Space vision. The book presents a system-level and technology-level description of future space networking and communications. The authors also expand the vision to interplanetary networks. The book spans hardware and software technologies for future space communication networks, also considering very modern paradigms like quantum technologies and Softwarization. In the book, the word “space� is intended in a wider sense than the usual “satellite communications�, including new and partially unexplored fields like quantum space communications, interplanetary communications, and extra-terrestrial Radio Access Networks (RANs). The book includes applications including Internet of Space Things, Tactile Internet/Digital twins for Space and discusses future challenges like those involved by the concept of “sustainable Space�. Provides an overview of the latest R&D advancements in the field of ICT technologies inherent to a New Space vision; Considers visions and perspectives of space technology, including a through overview of satellite communications; Presents a system-level overview of future space networking and communications.

This book provides a tutorial on quantum communication networks. The authors discuss current paradigm shifts in communication networks that are needed to add computing and storage to the simple transport ideas of prevailing networks. They show how these 'softwarized' solutions break new grounds to reduce latency and increase resilience. The authors discuss how even though these solutions have inherent problems due to introduced computing latency and energy consumption, the problems can be solved by hybrid classical-quantum communication networks. The book brings together quantum networking, quantum information theory, quantum computing, and quantum simulation.

Dieses Buch bietet ein Tutorial über Quantenkommunikationsnetze. Die Autoren erörtern aktuelle Paradigmenwechsel in Kommunikationsnetzen, die erforderlich sind, um die einfachen Transportkonzepte der vorherrschenden Netze um Rechen- und Speicherfunktionen zu ergänzen. Sie zeigen, wie diese "softwarisierten" Lösungen neue Wege beschreiten, um Latenzzeiten zu reduzieren und die Ausfallsicherheit zu erhöhen. Die Autoren erörtern, wie diese Lösungen trotz der ihnen innewohnenden Probleme aufgrund der eingeführten Rechenlatenz und des Energieverbrauchs durch hybride klassisch-quantische Kommunikationsnetze gelöst werden können. Das Buch bringt Quantennetzwerke, Quanteninformationstheorie, Quantencomputer und Quantensimulation zusammen.
