Quantum computing is an experimental method of computing that makes use of quantum-mechanical phenomena. Quantum computers would allow a bit to store a value of 0 and 1 simultaneously. They have the potential to solve problems that would take a classical computer longer than the age of the universe.
Quantum computing sounds like science fiction but the age of computing is not even at the end of the beginning. Traditional computing will soon reach a final barrier: Moore's law, which dictates that the amount of computing power you can squeeze into the same space will double every 18 months, is on course to run smack into a silicon wall by 2015, due to overheating, caused by electrical charges running through ever more tightly packed circuits.
