Quantum Computing

The combination of two of the twentieth century's most influential and revolutionary
scientific theories, information theory and quantum mechanics, gave rise to a radically new view of
computing and information. Quantum information processing explores the implications of using quantum
mechanics instead of classical mechanics to model information and its processing. Quantum computing
is not about changing the physical substrate on which computation is done from classical to quantum
but about changing the notion of computation itself, at the most basic level. The fundamental unit
of computation is no longer the bit but the quantum bit or qubit. This comprehensive introduction to
the field offers a thorough exposition of quantum computing and the underlying concepts of quantum
physics, explaining all the relevant mathematics and offering numerous examples. With its careful
development of concepts and thorough explanations, the book makes quantum computing accessible to
students and professionals in mathematics, computer science, and engineering. A reader with no prior
knowledge of quantum physics (but with sufficient knowledge of linear algebra) will be able to gain
a fluent understanding by working through the book.
