Description

For one-semester first courses in Quantum Computing. An introduction to the subject for undergraduate and graduate students in computer and electrical engineering, computer science, mathematics, and chemistry.

With a clear writing style and matter-of-fact approach, this rigorous yet accessible introduction is designed for students with a solid mathematical background but limited knowledge of physics and quantum mechanics. It introduces the quantum circuit model comprehensively-including the mathematical formalism required for quantum computing-using a methodical approach and an abundance of worked examples.

Features

  • Emphasis on the quantum circuit model-Focused presentation makes complex subject matter more accessible to students.
  • Phenomenological introduction to quantum computing-Motivates students to view the subject as a fundamentally new approach to computing, without the sophisticated mathematical apparatus needed for quantum mechanics.
  • Detailed analysis and step-by-step calculations-Illustrate the behavior of quantum circuits and algorithms.
  • Carefully selected set of mathematical and quantum mechanics concepts-Helps students become acquainted with the mathematical formalism required for quantum computing.
  • Detailed presentation of quantum algorithms-Demonstrates the logic behind the development of DeutschÕs problem, quantum Fourier transform, ShorÕs factoring algorithm, SimonÕs algorithm for phase estimation, and discrete logarithms evaluation problems, making them easier for students to grasp.
  • Thorough glossary-Includes 250+ definitions of concepts used throughout the text, plus a helpful index.
  • Substantial source materials-The inclusion of original literature, historical notes, summaries and conclusions in each chapter illustrates the evolution of key concepts.

Reader Review(s)

"This book arms to introduce the basics of quantum computing to advanced undergraduates anti beginning graduate students in electrical engineering arid computer science who have practically no background in quantum mechanics, but a fair level of mathematical sophistication. The basic ideas of quantum mechanics are developed in the context of two- and other finite state systems and illustrated by means of well-chosen physical examples. The heart of the book is devoted to a treatment of quantum gates and circuits, and following it, a discussion of quantum algorithms, including Shor's factoring algorithm and Grover's search algorithm. The purpose of the book is to make recent exciting developments in this emerging field accessible to the next generation of computer scientists as well as others without a traditional background in physics, End-of-chapter exercises, historical and biographical footnotes, a detailed glossary and a large number of references also make this a valuable text or reference work." - P.K. Aravind, Physics Department, Worcester Polytechnic Institute

"Quantum computing is a new promising area of research that investigates how the laws of quantum mechanics allow new forms of computation exponentially more efficient than any classical counterpart. This book aims at giving a gentle introduction to the basic concepts and mathematical techniques of this interdisciplinary research area to a readership with no previous background in quantum mechanics." - G. Massimo Palma, University of Milano and INFM

"Since it draws on same deed aspects of physics and mathematics, quantum computing can be a challenging subject to present. The Marinescus have done an admirable job of writing a highly readable and self-contained textbook on this important and fascinating new area of computer science. This is a thorough and very readable introduction to quantum computing. It should be especially useful as the text far an upper-level undergraduate or beginning graduate course aimed at computer science and engineering majors. The Marinescus have managed the difficult task of writing a book an quantum computing that is both technically complete and a pleasure to read. " - John Hayes, University of Michigan
