A quantum computer is a computer based on a computational model which uses quantum mechanics, which is a subfield of physics to study phenomena at the micro level. There has been a growing interest on quantum computing in the 1990´s and some quantum computers at the experimental level were recently implemented. Quantum computers enable super-speed computation and can solve some important problems whose solutions were regarded impossible or intractable with traditional computers.

This book provides a quick introduction to quantum computing for readers who have no backgrounds of both theory of computation and quantum mechanics. "Elements of Quantum Computing" presents the history, theories and engineering applications of quantum computing. The book is suitable to computer scientists, physicists and software engineers.

"This nice booklet is written for people who want to get an overview on computing and quantum computing without possessing precognition. It informs about what is done, can be done, and how to do in these fields. ... This book outlines well the history and present state of quantum computation." (K.-E. Hellwig, zbMATH 1361.81001, 2017)

"This is a chronicle of the lives of several physicists who shaped the history of Quantum Mechanics and subsequently, quantum computing. ... I recommend this book to physicists and history of physics majors." (Joseph J. Grenier, Amazon.com, April, 2016)
