Akama S. Elements of Quantum Computing. History, Theories and Engineering Applications

Springer, 2015. —133 p. ISBN: 978-3-319-08283-7.Now, computer technology is rapidly developed. It appears that the computer world is completely established. Certainly, the fact may be true according to current thinking but there seems to be a room for further developments. This is because we have some possibilities to realize a computer from a different point of view. One of such possibilities is the so-called quantum computer. It is a computer based on quantum mechanics, and it can do super speed computation. It is well known that theoretical possibilities of quantum computer have been argued since the beginning of the 1980’s.There has been a growing interest in the 1990’s, and some quantum computers at the experimental level were recently implemented. However, most people do not appear to be familiar with the field of quantum computer.
It is also true for experts working on computer science. The reason is that we cannot understand quantum computers without the background of quantum mechanics. It can be also pointed out that the foundations for quantum computer are not always obvious. We believe that one must study the basics of quantum computing systematically. Unfortunately, it is difficult to read most papers, including survey papers, on quantum computing. If there is a readable text book on the subject, many people will be able to understand (or study) quantum computing.The purpose of this book is to provide a quick introduction to quantum computing for the readers who have no backgrounds of both theory of computation and quantum mechanics. But to understand quantum computing, we need the knowledge of both computer science and quantum mechanics. One cannot easily learn relevant materials in both fields. Thus, we give an intuitive explanation of the material, and then add theoretical justification.Models of a Computer.
