商品描述

This book demonstrates that a quantum communication system using the coherent light of a laser can achieve performance orders of magnitude superior to classical optical communications

Quantum Communications provides the Masters and PhD signals or communications student with a complete basics-to-applications course in using the principles of quantum mechanics to provide cutting-edge telecommunications. Assuming only knowledge of elementary probability, complex analysis and optics, the book guides its reader through the fundamentals of vector and Hilbert spaces and the necessary quantum-mechanical ideas, simply formulated in four postulates. A turn to practical matters begins with and is then developed by:

· development of the concept of quantum decision, emphasizing the optimization of measurements to extract useful information from a quantum system;

· general formulation of a transmitter–receiver system

· particular treatment of the most popular quantum communications systems―OOK, PPM, PSK and QAM;

· more realistic performance evaluation introducing thermal noise and system description with density operators;

· consideration of scarce existing implementations of quantum communications systems and their difficulties with suggestions for future improvement; and

· separate treatment of quantum information with discrete and continuous states.

Quantum Communications develops the engineering student’s exposure to quantum mechanics and shows physics students that its theories can have practically beneficial application in communications systems. The use of example and exercise questions (together with a downloadable solutions manual for instructors) will help to make the material presented really sink in for students and invigorate subsequent research.

商品描述(中文翻譯)

這本書展示了使用激光的相干光量子通信系統可以實現比傳統光學通信性能高出數個數量級的優越性。

《量子通信》為碩士和博士信號或通信專業的學生提供了一個完整的從基礎到應用的課程,使用量子力學原理提供尖端的電信技術。本書假設讀者只具備基本的概率、複分析和光學知識,通過四個公理簡單地介紹了向量和希爾伯特空間的基礎以及必要的量子力學思想。實際應用方面的轉變始於以下內容並進一步發展:

· 發展量子決策的概念,強調從量子系統中優化測量以提取有用信息;
· 一般性地制定發射機-接收機系統;
· 特別處理最流行的量子通信系統——OOK、PPM、PSK和QAM;
· 引入熱噪聲和密度算子系統描述的更現實性能評估;
· 考慮現有量子通信系統的稀缺實現及其困難,並提出未來改進的建議;
· 分別處理離散和連續狀態的量子信息。

《量子通信》拓展了工程學生對量子力學的接觸,並向物理學生展示了其理論在通信系統中的實際應用。書中的例子和練習問題(以及供教師下載的解答手冊)將有助於學生真正理解所呈現的材料,並激發後續的研究。
