The Path to A Quantum Computer
Highly recommended-when the revolution comes don't say no one warned you' Scotland on Sunday
The newest Pentium chip powering PCs and laptops contains 40 million electronic switches packed onto a piece of silicon about the size of a thumbnail. Several years from now, if this incredible shrinking continues, a single chip will hold a billion switches, then a trillion. The logical culmination is a computer in which the switches are so tiny that each consists of an individual atom. At that point something miraculous happens: Quantum mechanics kick in. Anyone who follows the science news or watches 'Star Trek' has at least a notion of what that means: particles can be in two or more places at once. Atoms obey a peculiar logic of their own - and if it can be harnessed society will be transformed. Problems that would now take forever would be solved almost instantly. Quantum computing promises nothing less than a shortcut through time.
“Fascinating and highly accessible-Unpicking the complexities of the subject is not easy, but Johnson has done a fine job of it. Johnson's excellent book is highly recommended-when the revolution comes don't say no one warned you'”

“Lucid and accessible-[written with] a beguiling combination of clarity and enthusiasm'”
“Johnson is one of the best science journalists writing today”
