This book highlights state-of-the-art qubit implementations in semiconductors and provides an extensive overview of this newly emerging field. Semiconductor nanostructures have huge potential as future quantum information devices as they provide various ways of qubit implementation (electron spin, electronic excitation) as well as a way to transfer quantum information from stationary qubits to flying qubits (photons). Therefore, this book unites contributions from leading experts in the field, reporting cutting-edge results on spin qubit preparation, read-out and transfer. The latest theoretical as well as experimental studies of decoherence in these quantum information systems are also provided. Novel demonstrations of complex flying qubit states and first applications of semiconductor-based quantum information devices are given, too.

Biography
Fritz Henneberger currently occupies the Chair of Photonics at Humboldt-Universität zu Berlin. His research comprises semiconductor lasers, photonic materials and nanostructures, as well as elementary excitations and their dynamical interactions in semiconductors. He is a recipient of the Heinrich-Hertz Award of the Germany Physical Society. Henneberger has been a staff member of the Ioffe Institute, Leningrad, for several years. He has been a visiting professor at the Optical Science Center, University of Arizona, USA, and Kyoto University, Japan.
"Undoubtedly the book represents the interest for scientists working in this field and related physics fields. It is not a textbook, but [a detailed study] of the suggested material is very important for postgraduate students specializing in the modern optics of nanosubjects and theorists studying quantum computer theory."
—Igor A. Merkulov, University of Tennessee, USA"This book provides a timely summary of the state of the art from established groups around the world and will serve as a critical reference for researchers and students working to advance the frontier. The editors have done an excellent job in collecting and assembling the topics and authors for the most important areas."
—Duncan G. Steel, University of Michigan, USA
