Akira Furusawa Libri

The book delves into the nature of quantum states of light, particularly focusing on single photon states through a wave perspective, illustrating the concept of quantum complementarity. It explores the creation of light waves from photons and demonstrates how optical waves arise from the superposition of a vacuum and a single photon. Additionally, it addresses squeezed states of light as longitudinal waves and examines Schrödinger's cat states as examples of macroscopic superpositions, providing a comprehensive understanding of these complex concepts.

Unique in that it is jointly written by an experimentalist and a theorist, this monograph presents universal quantum computation based on quantum teleportation as an elementary subroutine and multi-party entanglement as a universal resource. Optical approaches to measurement-based quantum computation are also described, including schemes for quantum error correction, with most of the experiments carried out by the authors themselves. Ranging from the theoretical background to the details of the experimental realization, the book describes results and advances in the field, backed by numerous illustrations of the authors' experimental setups. Aimed at researchers, physicists, and graduate and PhD students in physics, theoretical quantum optics, quantum mechanics, and quantum information.
