The International Conference on Quantum Information Processing and Communication (QIPC) 2013 was organized within the QUIE2T Coordination Action (Quantum Information and Entanglement Enabled Technologies), an FP7 Coordination Action to support QIPC in Europe. It covered a broad range of topics on quantum information and quantum communication, physical realizations of quantum systems for information technologies and topical subjects such as quantum enhanced measurements, foundations of quantum information, quantum simulations and many-body systems.

Research in quantum communication requires knowledge of the information theory and teleportation of information in any physical form using the quantum field as media of all different processes and aspects on the managing of their information, their boson processing and their technologies. Likewise, one of the most important principles in researching is the quantum intertwining to define the management of communication of the quantum type. Other aspects related to the design of technologies to the quantum communication base and their development on transceptor models of Bose-Einstein observation nature to form a quantum laser wave of atoms. This quantum wave is a wave-links chain that defines and determines the quantum communication. Quantum computing models are very useful to establish the programming order required in the quantum communication processes. The present book is a compilation of the chapters that cover several of these themes and in other cases, put the field theories to test regarding what is quantum communication and its technologies.

Satellite-based quantum network is currently a key research topic. Working with a quantum network requires the understanding of many advanced fields, especially quantum electronics and communication. A quantum communication system utilizes quantum information processes using quantum bits or qubits, similar to a classical communication system using ordinary bits, but with a different underlying physics. The coupling of qubits based on quantum entanglements and superposition is a necessary process for manipulation of quantum information and, hence, quantum communication. Such processes are led by some logical operations with the help of quantum logic gates that transform qubit states. The proposed chapter moves in this direction and explores the operations and designs of quantum logic gates using qubits required for quantum communication processes. Algorithms are created and the quantum communication processes are utilized for their execution applicable to satellite-based quantum networks.
