D-Wave out of Canada has just sold the first of its commercial quantum computers and they sold it to Lockheed-Martin. However, it wasn't as easy as your average sale. Despite the fact that D-Wave managed to make the sale, the company had to do it despite a debate over whether it truly was a quantum computer. Back in February 2007 D-Wave demonstrated a machine that could solve problems regular computers are incapable of solving, in principle that is. The reason it is only in principle is because the tests run on the computer were not impossible on a regular computer. This created a fair bit of doubt among some that the chip was actually performing quantum-mechanical computations. The computer works differently than the regular "gate model" of quantum computing where a series of quantum bits can be encoded as either 0, 1 or both simultaneously. D-Wave's machine uses something researchers are calling "adiabatic quantum computing" or "quantum annealing"
