Controversial Canadian company D-Wave, which has long been press claims on "commercial" quantum computing, can now claim to have sold a machine.
Even if the debate still rages on the question of whether its technology is truly quantum computing, the company said that Lockheed-Martin will buy his machine a D-Wave for a rumour 10 million.
Exactly what the a D-Wave is, however, is still in place in the air - as is the link between its marketing department writes and what the company actually built. For example, while that the company described the machine as offering 128 qubit of treatment, other physicists say D-Wave in Nature paper shows that the "non-classical effects" (i.e., behaviors that seem to occur at the quantum level) in an eight-qubit system.

If the machine was actually performing quantum computing, this would represent yet a great leap forward, since the most recent work on quantum computing is only able to demonstrate a few qubits at best.
According to MIT Professor of computer science and electrical engineering Scott Aaronson, a critic of long date company, article Nature of D-Wave really goes beyond its previous preference for paper glossy-but-inaccurate press releases and shows a quantum effect.
"In the new work, they apply an annealing to eight coupled qubits arranged in a 1 D string, and then plot the probability of a particular base state, time running experience again and again and in stopping at intermediate points." They then watch the dependence of the curve of probability versus time on a third parameter, the temperature and request that they can explain the influence of the curve temperature by numerical simulation assumes that quantum mechanics but not one that assumes classical simulated annealing, "written Aaronson."
This dismantling, demonstrated the quantum effect - quantum annealing - is apparently present in the D-Wave demonstration, but the extent to which this effect is currently commercially useful to solve the problems of the real world is less clear.
For example, it is agreed still as D-Wave techniques do not generate entanglement, suggesting that they still limit themselves to problems which are also towable computers "classic". The D-Wave application is that it can resolve such problems more quickly than a classical computer. In summary its nature, its claim is as follows:
"Such a system can provide a physical practice means to implement a quantum algorithm, possibly enabling more effective approaches to solve certain classes of combinatorial optimization problems hard."
While Lockheed-Martin?
It looks a little like defence giant is going to tilt in a sum of money in exchange for acting as a development platform for D-Wave. His money will give access to the machine itself (that would evaluate to itself or not quantum effects are working, and whether the implementation of a D-Wave can exceed a classical computer problems more difficult than Sudoku solutions).

D - Wave Gets a client that systematically deals with complex computing problems, knows the constraints in the "conventional" solutions of such problems and probably had the intellectual influence on the spot to help to express these issues in terms that can handle a "quantum" computer.
While more important that association of D-Wave with Google, the contract Lockheed-Martin is therefore even more R & D current that a product at the edge of marketing.
For another interesting and brief discussion on the appropriateness of the work of D-Wave, read the discussion of Dave Bacon on Quora. ®
