Still in only the most advanced laboratories the future of computing seems to lie in new technologies that will replace the current type of semi-conductors. These technologies, lumped together under the term Quantum Devices. For the first time, the leading reserchers from around the world have gotten together to produce a book containing all of the promising areas that are being worked on, summarizing the work up to date, and giving some indication of the direction of future research.

Up until now the ever increasing speed of computers has been following Moore's law which states that the computing power of a CPU will double every 1.5 years at half the price. But in about nine more doublings there is a brick wall, the devices built into the chip will be one atom wide and you can't get any smaller than that with semi-conductors.

The basic concepts of quantum computing go back to the 80's. But the actual construction of devices that could perform the basic tasks such as quantum logic gates has proven more difficult, There are several schemes that have shown promise, but each has stumbled over roadblocks and difficulties. In turn each has provided spin offs into both computing and other areas as well.

Here in one book is the story of the state of the art.
