A Shortcut Through Time The Path to the Quantum Computer

In this remarkably illustrative and thoroughly accessible look at one of the most intriguing frontiers in science and computers, award-winningNew York Timeswriter George Johnson reveals the fascinating world of quantum computingthe holy grail of super computers where the computing power of single atoms is harnassed to create machines capable of almost unimaginable calculations in the blink of an eye. As computer chips continue to shrink in size, scientists anticipate the end of the road: A computer in which each switch is comprised of a single atom. Such a device would operate under a different set of physical laws: The laws of quantum mechanics. Johnson gently leads the curious outsider through the surprisingly simple ideas needed to understand this dream, discussing the current state of the revolution, and ultimately assessing the awesome power these machines could have to change our world. From the Trade Paperback edition.
