Building a quantum computer is one of the great scientific and engineering challenges of our time. A quantum processor stores and manipulates an amount of information that is exponential in the number of elementary bits, in contrast to classical information processing which is linear in the bit number. A quantum computer represents the most general type of information processor allowed by the known laws of physics, and it has been proven that a quantum computer can solve certain problems that are classically intractable. Efforts to build quantum processors are bolstered by the theoretical results of quantum fault tolerance, which prove that, in principle, decoherence of quantum states is not a fundamental obstacle to quantum computing as long as the error rate is below a threshold.
