On Wednesday, D-Wave Systems made history by announcing the sale of the world's first
commercial quantum computer. The buyer was Lockheed Martin Corporation, who will use the
machine to help solve some of their "most challenging computation problems." ...
... D-Wave One uses a superconducting 128-qubit (quantum bit) chip, called
Rainier, representing the first commercial implementation of a quantum
processor. An early prototype, a 16-qubit system called Orion, was demonstrated
in February 2007. At the time, D-Wave was talking about future systems based on
512-qubit and 1024-qubit technology, but the 128-qubit Rainier turned out to be
the company's first foray into the commercial market. ...
128 quantum bits sounds like a lot, but it is less than it seems,
because this is not a general purpose quantum computer, though it can
emmulate a general purpose quantum computer with considerably fewer
quantum bits.
