Quest for the Quantum Computer

Synopses & Reviews

Publisher Comments:

Taking readers to the cutting edge of physics, mathematics, and computer science, Julian Brown tells the dramatic story of the groundbreaking efforts to create a fundamentally new kind of computer that would be astronomically more powerful than today's machines. In 1998, a team of researchers announced they had produced the world's first quantum computer in a cup of chloroform. In fascinating, fully accessible detail, Brown explains the ideas that led up to this accomplishment and explores the mind-stretching implications of this leap into the bizarre world of quantum physics. The Quest for the Quantum Computer is a riveting look at what promises to be one of the most important scientific and technological ideas of the twenty-first century.

Review:

"A fascinating and entertaining read from start to finish." Ed Hinds, New Scientist

Review:

"A masterful piece of scientific exposition." Paul Davies, author of The Fifth Miracle

Review:

"Exciting and educational...a road map for the future." Lynn Yarris, San Jose Mercury News

Review:

"Brown, a writer for New Scientist, covers an immense variety of subjects in this book, most of which touch in some way on quantum physics, and he devotes a considerable amount of effort to making his exposition understandable. Some of the analogies he uses to simplify complex ideas work well, while others left this reader more confused than before – possibly reflecting a lack of strong background in physics but still a potential problem for other readers. Brown also throws in a substantial philosophical treatment of artificial intelligence. An interesting topic but not easy reading; for academic and larger public libraries." Hilary Burton, Library Journal

Review:

"The English-speaking world has plenty of books explaining computers, quantum theory and the attendant wacky philosophical implications, but Brown transcends these categories, showing how physics relates to computation and how their alliance affects the future of both. His enthusiastic, patient explanations of fairly difficult mathematics distinguishes his book." Publishers Weekly
