Description
A thorough exposition of quantum computing and the underlying concepts of quantum physics, with explanations of the relevant mathematics and a large number of examples.
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 the use of quantum mechanics as an alternative of classical mechanics to model information and its processing. Quantum computing isn’t about changing the physical substrate on which computation is done from classical to quantum but about changing the notion of computation itself, on the most basic level. The fundamental unit of computation is no longer the bit however 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 of the relevant mathematics and offering a large number of 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 without a prior knowledge of quantum physics (but with sufficient knowledge of linear algebra) will be capable to gain a fluent understanding by working during the book.
