The Feynman processor: Quantum entanglement and the computing revolution [Book Review]

During the second half of this century we have witnessed staggering progress in the development of information technology. At present, the pace of progress shows no sign of slowing. But in the early twenty-first century, conventional integrated-circuit technology will approach the fundamental limitations imposed by the atomic size scale. At that stage, continued improvement in computing performance, and the continued expansion of the world economy, may hinge on the development of radically new methods for processing information.
