This open access book makes quantum computing more accessible than ever before. A fast-growing
field at the intersection of physics and computer science quantum computing promises to have
revolutionary capabilities far surpassing classical computation. Getting a grip on the science
behind the hype can be tough: at its heart lies quantum mechanics whose enigmatic concepts can
be imposing for the novice. This classroom-tested textbook uses simple language minimal math
and plenty of examples to explain the three key principles behind quantum computers:
superposition quantum measurement and entanglement. It then goes on to explain how this
quantum world opens up a whole new paradigm of computing. The book bridges the gap between
popular science articles and advanced textbooks by making key ideas accessible with just high
school physics as a prerequisite. Each unit is broken down into sections labelled by difficulty
level allowing the course to be tailored to the student's experience of math and abstract
reasoning. Problem sets and simulation-based labs of various levels reinforce the concepts
described in the text and give the reader hands-on experience running quantum programs. This
book can thus be used at the high school level after the AP or IB exams in an extracurricular
club or as an independent project resource to give students a taste of what quantum computing
is really about. At the college level it can be used as a supplementary text to enhance a
variety of courses in science and computing or as a self-study guide for students who want to
get ahead. Additionally readers in business finance or industry will find it a quick and
useful primer on the science behind computing's future.
