New paradigm of performing quantum information tasks, such as quantum information transfer, quantum cloning and others, without direct control of the whole quantum system but using our knowledge of it has increased the need of tools to understand in details the behavior of many body quantum system as we find them in nature
New goals of the quantum information community lead to an unavoidable exchange of knowledge with other communities that already have the know-how and the insight to address such problems, such as the condensed matter, computational physics or quantum chaos communities
Applying known techniques and developing new ones from a quantum information perspective have already produced fast and unexpected developments in these fields
In the last years a growing attention has been dedicated to many body quantum systems from the point of view of quantum information. Indeed, after the initial investigation of simple systems as single or two qubits, the need of understanding the characteristics of a realistic quantum information device leads necessarily to the study of many body quantum systems. These studies are also driven by the very fast development of experiments which in the last years reach the goal of coherent control of a few qubits with a roadmap for further scaling and improvement of coherent control and manipulation techniques.
This book gives a selection of current research topics in the field of quantum information for many body quantum systems together with open problems.
