Quantum Continuous Variables: A Primer of Theoretical Methods

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.

The volume includes coverage of entanglement theory and quantum information protocols, and their connection with relevant experimental set-ups. General techniques for non-Gaussian manipulations also emerge as the treatment unfolds, and are demonstrated with specific case studies.

This book will be of interest to graduate students looking to familiarise themselves with the field, in addition to experienced researchers eager to enhance their understanding of its theoretical methods. It will also appeal to experimentalists searching for a rigorous but accessible treatment of the theory in the area.

《量子連續變量》介紹了連續變量量子系統的理論，從基於高斯態框架的基礎到現代發展，包括其在量子信息和即將到來的量子技術中的應用。這本新書通過一種新的方法，既包括希爾伯特空間描述，也包括相位描述，深入廣泛地探討了高斯態、操作和動力學的理論。

該書涵蓋了純化理論和量子信息協議，以及它們與相關實驗設置的聯繫。非高斯操作的一般技術也在處理過程中出現，並通過具體案例進行了演示。

這本書將對研究生感興趣，他們希望熟悉這個領域，同時也對經驗豐富的研究人員有吸引力，他們渴望加深對該領域理論方法的理解。對於尋求嚴謹但易於理解的理論處理的實驗者來說，這本書也很有吸引力。
