This text is a comprehensive introduction to the main ideas and techniques

of the field of quantum computation and quantum information. Until now,

the rapid rate of progress and its cross-disciplinary nature have made it

difficult for newcomers to the field to obtain a broad overview of the most

important techniques and results.

Michael Nielsen and Isaac Chuang ask the question: what are the ultimate

physical limits to computation and communication? They describe in detail

such remarkable effects as fast quantum algorithms, quantum teleportation,

quantum cryptography and quantum error-correction. A wealth of

accompanying figures and exercises illustrate and develop the material in

more depth. A special feature is the tutorial introductions to quantum

mechanics and computer science included in Part I of the book, ensuring that

the subject is accessible even without a background in physics or computer

science. In Part II, the authors present quantum computation, and describe

what a quantum computer is, how it can be used to solve problems faster

than familiar 'classical' computers, and the real-world implementation of

quantum computers. Part III concludes the book with an in-depth treatment

of quantum information, explaining how quantum states can be used to

perform remarkable feats of communication, together with a discussion of

how it is possible to protect quantum states against the effects of noise.

This exciting text will be of interest to beginning graduate students and

researchers in physics, computer science, mathematics, and electrical

engineering with an interest in quantum computation and quantum

information, and may be used as a text in courses on the subject.

Michael Nielsen is a Postdoctoral Research Fellow at the University of

Queensland. He was born in Brisbane, Australia, and received his education

at the University of Queensland, obtaining postgraduate degrees in

Mathematics and Physics before receiving his Ph.D. in Physics as a

Fulbright Scholar at the University of New Mexico. He has held a visiting

position at the Los Alamos National Laboratory, and was the Tolman

Postdoctoral Fellow at the California Institute of Technology.

Isaac Chuang is with IBM Research, and also serves as a consulting professor

at Stanford University. He received his doctorate in Electrical Engineering

from Stanford University, where he was a Hertz Foundation Fellow, and

also holds degrees in Physics and in Electrical Engineering from MIT. Dr.

Chuang is a native of Louisville, Kentucky and enjoys reading, hiking, and

playing his violin.
