This electrical Engineering text presents the concepts and workings of quantum information processing systems in a straightforward, practical way. The book is written in a style that helps readers who are not familiar with non-classical information processing to understand the concepts. No technical knowledge is required beyond classical Physics, basic digital design, and some exposure to linear algebra. Quantum computing: a beginner introduction presents each topic in a tutorial style with examples, illustrations, and diagrams To clarify the material. Quantum Gates and circuits, algorithms, error correction, and cryptography are covered. The emphasis of the book is on understanding the principles and applications of quantum computing using only essential math all relevant mathematical concepts are introduced at appropriate places in the text.
