All this happened, more or less.

The Canadian company on Tuesday gave a public demonstration of Orion, its quantum computer, at the Computer History Museum in Mountain View, Calif. D-Wave said it is going to try to sell computing services to corporate customers in the first quarter of 2008.

Quantum computers, which researchers have experimented with for years but which haven't yet existed outside of the laboratory, are radically different than today's electronic computers. D-Wave's computer is based around a silicon chip that houses 16 "qubits," the equivalent of a storage bit in a conventional computer, connected to each other. Each qubit consists of dots of the element niobium surrounded by coils of wire.

When electrical current comes down the wire, magnetic fields are generated, which, in turn, causes the change in the state of the qubit. Because scientists understand how niobium will react to magnetic fields and calculate the exact pattern and timing of the magnetic fields created, the pattern of changes exhibited by the niobium can then be translated into an answer that humans can understand.

But is there a market for renting computing cycles? Sun Microsystems a few years ago opened up a server farm for hire for chemical and pharmaceutical companies. It has found few takers.
