This book is an introductory text to the field of Continuous Variable Quantum Computing and Quantum Information. Continuous variables (CVs) offer an extremely important alternative to the usual qubit substrate, as it involves easy to analyze Gaussian statistics, off-the-shelf experimental components and near universal deterministic quantum gates and operations. For communications, CVs can be easily adapted to the current telecommunication infrastructures and components, offering much higher communication rates. The contents intend to cover the most exciting topics in this field.
