A Short Introduction to Quantum Information and Quantum Computation

Quantum information and computation is a rapidly expanding and cross-disciplinary subject. This book gives a self-contained introduction to the field for physicists, mathematicians and computer scientists who want to know more about this exciting subject. After a step-by-step introduction to the quantum bit (qubit) and its main properties, the author presents the necessary background in quantum mechanics. The core of the subject, quantum computation, is illustrated by a detailed treatment of three quantum algorithms: Deutsch, Grover and Shor. The final chapters are devoted to the physical implementation of quantum computers, including the most recent aspects, such as superconducting qubits and quantum dots, and to a short account of quantum information. Written at a level suitable for undergraduates in physical sciences, no previous knowledge of quantum mechanics is assumed, and only elementary notions of physics are required. c1.pdf......Page 1 c2.pdf......Page 2 c3.pdf......Page 3 1.pdf......Page 5 2.pdf......Page 25 3.pdf......Page 45 4.pdf......Page 65 5.pdf......Page 85 6.pdf......Page 105 7.pdf......Page 125 8.pdf......Page 145 9.pdf......Page 165 10.pdf......Page 170
