"Recently there has been a tremendous media buzz about the coming quantum computing revolution. Chris Bernhardt has masterfully crafted this short book to teach the basics to anyone interested in this fascinating field. The reader is not expected to know more than high school mathematics, and with that, this extremely accessible book will guide you through the many parts of quantum computing." – Noson S. Yanofsky, Professor, Brooklyn College, Department of Computer and Information Sciences; coauthor of Quantum Computing for Computer Scientists; and author of The Outer Limits of Reason

"Bernhardt has written a clear, no-nonsense introduction to quantum computing and information -- one that takes beginners by the hand and leads them up to a working understanding of quantum teleportation, Bell's inequality, Simon's algorithm, and more. I'll enthusiastically recommend this book to the next beginner who asks me." – Scott Aaronson, David J. Bruton Centennial Professor of Computer Science and Director of the Quantum Information Center at the University of Texas at Austin; author of Quantum Computing Since Democritus

"Will the bit ever be replaced by the qubit? Quantum computers now loom on the technical horizon. This essential text opens the door for technical readers to walk through a gallery of quantum effects leading to the basics of quantum computing." – Keewatin A. Dewdney, Professor of Computer Science, University of Western Ontario

Chris Bernhardt is Professor of Mathematics at Fairfield University and the author of
