Quantum Computing: An Applied Approach 2nd ed. 2021 Edition

This book integrates the foundations of quantum computing with a hands-on coding approach to this emerging field; it is the first to bring these elements together in an updated manner. This work is suitable for both academic coursework and corporate technical training.

The second edition includes extensive updates and revisions, both to textual content and to the code. Sections have been added on quantum machine learning, quantum error correction, Dirac notation and more. This new edition benefits from the input of the many faculty, students, corporate engineering teams, and independent readers who have used the first edition.

This volume comprises three books under one cover: Part I outlines the necessary foundations of quantum computing and quantum circuits. Part II walks through the canon of quantum computing algorithms and provides code on a range of quantum computing methods in current use. Part III covers the mathematical toolkit required to master quantum computing. Additional resources include a table of operators and circuit elements and a companion GitHub site providing code and updates.

Jack D. Hidary is a research scientist in quantum computing and in AI at Alphabet X, formerly Google X.

"Quantum Computing will change our world in unexpected ways. Everything technology leaders, engineers and graduate students need is in this book including the methods and hands-on code to program on this novel platform."

--Eric Schmidt, PhD, Former Chairman and CEO of Google; Founder, Innovation Endeavors

這本書將量子計算的基礎與實踐編碼方法結合在一起，是第一本以更新的方式將這些元素結合在一起的書籍。這本書適用於學術課程和企業技術培訓。

第二版包括廣泛的更新和修訂，包括文本內容和程式碼。新增了關於量子機器學習、量子錯誤修正、狄拉克符號等內容的章節。這個新版本受益於許多教職員、學生、企業工程團隊和獨立讀者對第一版的使用和反饋。

這本書包含三本書的內容：第一部分概述了量子計算和量子電路的基礎知識。第二部分介紹了量子計算算法的典範並提供了目前使用的各種量子計算方法的程式碼。第三部分介紹了掌握量子計算所需的數學工具。附加資源包括運算子和電路元素的表格，以及一個提供程式碼和更新的GitHub網站。
