The Feynman processor

the long version

"In The Feynman Processor, quantum physicist Gerard J. Milburn describes the astounding principles of the quantum world that are about to revolutionize the world of computers - including a concept created by the legendary American physicist Richard Feynman, which proves that the most important principle in a quantum computer is that of probability amplitude, a rule that has become known as "Feynman's Rule." It is Feynman's Rule that gives the quantum computer its nickname, the Feynman Processor, and that will endow computers with an enormous range of powerful new capabilities." "He shows why conventional computers can't go on getting faster and smaller forever and how the unpredictability of matter at this level has enabled scientists to rethink the way that we could design, build, and use the new "quantum computers." Finally, Milburn takes us into the near future, when physicists and computer scientists will build new and incredible devices that will deliver a world of lightning-fast computers, unbreakable codes, and even the beginnings of Star Trek-like matter teleportation."--Jacket.
