Quantum Computation and Quantum Information

well-perused copy of Nielsen and Chuang is, as always, close at hand as I write this. It appears that the material that Mike and Ike chose to cover, which was a lot, has turned out to be a large portion of what will become the eternal verities of this still-young field. When another researcher asks me to give her a clear explanation of some important point of quantum information science, I breathe a sigh of relief when I recall that it is in this book - my job is easy, I just send her there.' David DiVincenzo, IBM T. J. Watson Research Center 'If there is anything you want to know, or remind yourself, about quantum information science, then look no further than this comprehensive compendium by Ike and Mike. Whether you are an expert, a student or a casual reader, tap into this treasure chest of useful and well presented information.' Artur Ekert, Mathematical Institute, University of Oxford 'Nearly every child who has read Harry Potter believes that if you just say the right thing or do the right thing, you can coerce matter to do something fantastic. But what adult would believe it? Until quantum computation and quantum information came along in the early 1990s, nearly none. The quantum computer is the Philosopher's Stone of our century, and Nielsen and Chuang is our basic book of incantations. Ten years have passed since its publication, and it is as basic to the field as it ever was. Matter will do wonderful things if asked to, but we must first understand its language. No book written since (there was none before) does the job of teaching the language of quantum theory's possibilities like Nielsen and Chuang's.' Chris Fuchs, The Perimeter Institute for Theoretical Physics 'Nielsen and Chuang is the bible of the quantum information field. It appeared 10 years ago, yet even though the field has changed enormously in these 10 years - the book still covers most of the important concepts of the field.' Lov Grover, Bell Labs 'Quantum Computation and Quantum Information, commonly referred to as 'Mike and Ike', continues to be a most valuable resource for background information on quantum information processing. As a mathematically-impaired experimentalist, I particularly appreciate the fact that armed with a modest background in quantum mechanics, it is possible to pick up at any point in the book and readily grasp the basic ideas being discussed. To me, it is still 'the' book on the subject.' David Wineland, National Institute of Standards and Technology, Boulder, Colorado
