Google, NASA, and the Universities Space Research Association have announced that they'll collaborate in purchasing the second $10 million dollar D-Wave Two quantum computing system on the market. The system will deploy to NASA's Ames Research Center, and should be online by the fall of this year, where it'll be put to work solving particular types of problems. Before we delve into that, let's talk a bit about what a quantum computer is -- and what it isn't. Quantum Annealment A quantum computer is a computer that uses quantum information to store data. In a classical computer, data is stored electrically,... Read more...
Over the past couple of weeks, a company names D-Wave Systems made some news after announcing that they had developed what was supposedly the world's first commercial quantum computer.  And now D-Wave's claims have come under fire because they've failed to submit their findings for peer review. This story on CNN Tech discusses some of the finer details of the situation. "Quantum computing is such an elusive goal that even the company claiming to have the "world's first commercial quantum computer" acknowledged it isn't entirely sure the machine is performing true quantum calculations....

We've all heard of bits and bytes.  Ever hear of a qubit?  So it goes like this.  Bits, as we traditionally know them, are either in a 1 or 0 state.  Right, well, a qubit exists in a quantum state. So for example, it can be either 1 or 0 or both or somewhere in between.  This is the crux of quantum computing.  Sufficiently confused?  What if we told you a quantum computer or a system built with a quantum computing 16 qubit engine could carry out 64,000 calculations simultaneously in parallel universes?  Oh and a machine built with a hundreds of qubits...
