Features Provides the first systematic graduate-level textbook for the field of quantum continuous variables Explores applications to entanglement generation, quantum teleportation, classical channel capacities, quantum metrology, and quantum key distribution, including a full proof of the recently proven Gaussian additivity conjecture, Describes, in detail, a list of experimental platforms where the formalism applies Includes 70 problems for the reader with accompanying solutions Summary Quantum Continuous Variables introduces the theory of continuous-variable quantum systems, from its foundations based on the framework of Gaussian states to modern developments, including its applications to quantum information and forthcoming quantum technologies. This new book addresses the theory of Gaussian states, operations, and dynamics in great depth and breadth, through a novel approach that embraces both the Hilbert space and phase descriptions.
