D-Wave Systems claims to have produced the first quantum computer, a device that could carry out multiple calculations simultaneously using different quantum states of the system. Proposed by Nobel Prize winner Richard Feynman and elaborated on by David Deutsch in the 1980s, quantum computing has made slow progress because of the difficulty of building systems with more than a few quantum bits, or "qubits," and then maintaining them in a "coherent" state so that the different quantum states can operate at the same time and for long enough to carry out useful work. To get a long "decoherence time," quantum computers have had to be completely isolated from the outside world. Funded by venture capitalists, D-Wave is the only commercial quantum computing company, having raised $44 million US Dollars from partners. It demonstrated a 16-qubit computer, called Orion, in February, but scientists have been skeptical that D-Wave demonstrated true quantum computing, as no results have been published in peer-reviewed journals. This Monday's demonstration will however be overlooked by a Google scientist, to verify if this is a true quantum computer.
