Absalom, Absalom!

One of the most cited books in physics of all time, Quantum Computation and Quantum Information remains the best textbook in this exciting field of science. This 10th anniversary edition includes an introduction from the authors setting the work in context. This comprehensive textbook describes such remarkable effects as fast quantum algorithms, quantum teleportation, quantum cryptography and quantum error-correction. Quantum mechanics and computer science are introduced before moving on to describe what a quantum computer is, how it can be used to solve problems faster than classical computers and its real-world implementation. It concludes with an in-depth treatment of quantum information. Containing a wealth of figures and exercises, this well-known textbook is ideal for courses on the subject, and will interest beginning graduate students and researchers in physics, computer science, mathematics, and electrical engineering. This Is An Introduction To The Main Ideas And Techniques Of The Field Of Quantum Computation And Quantum Information. It Asks The Question: What Are The Ultimate Physical Limits To Computation And Communication? Fundamental Concepts -- Introduction And Overview -- Introduction To Quantum Mechanics -- Introduction To Computer Science -- Quantum Computation -- Quantum Circuits -- The Quantum Fourier Transform And Its Applications -- Quantum Search Algorithms -- Quantum Computers: Physical Realisation -- Quantum Information -- Quantum Noise, Open Quantum Systems, And Quantum Operations -- Distance Measurement For Quantum Information -- Quantum Error-correction -- Entropy And Information -- Quantum Information Theory -- Notes On Basic Probability Theory -- Group Theory -- Approximating Quantum Gates: The Solovay-kitaev Theorem -- Number Theory -- Public-key Cryptography And The Rsa Cryptosystem -- Proof Of Lieb's Theorem. Michael A. Nielsen & Isaac L. Chuang. Previous Ed.: 2000. Includes Bibliographical References (p. [649]-664) And Index. A decade after it was first published, this book remains the best textbook in this exciting field. This 10th anniversary edition includes an introduction from the authors setting the work in context.
