Quantum Computing for the Quantum Curious

Published as an open access title, this book aims to put quantum computing within reach of readers new to the subject. The field sits where physics and computer science meet, and its supporters expect quantum machines to go well beyond 'classical' computers. The science behind that excitement is hard to penetrate, however, because it rests on quantum mechanics, a body of ideas that can feel forbidding to beginners.

Written in plain language with little mathematics and many worked examples, the book is a classroom-tested textbook. It introduces three foundational principles of quantum computers: superposition, quantum measurement, and entanglement. It then shows how this quantum behavior gives rise to a new way of computing. The text is meant to sit between popular science writing and advanced textbooks, and it assumes only high school physics.

Each unit is divided into sections marked by difficulty, so instructors and students can choose a route that matches their comfort with mathematics and abstract reasoning. Problem sets and simulation-based labs at several levels accompany the text and let readers run quantum programs themselves.

The book serves several audiences. High school teachers can use it after students finish AP or IB examinations, in an extracurricular club, or as a resource for independent projects. At the college level it works as a supplement across science and computing courses, or as a self-study guide for students who want to get ahead. Professionals in business, finance, and industry will find it a concise introduction to the science behind the future of computing.
