This book is aimed at people who simply know the basics of computer programming. It does not require any notion of physics and allows its readers to understand with total accuracy the use that could be made of a quantum computer, by explaining how to write a software to emulate its operation. The resulting knowledge is of vital importance to investors too, because it allows them to judge independently on the risk of investing in this technology.
