That does depend on what you call a quantum computer. D-wave isn't what most physicists think of when hearing the word quantum computer(which refers to a universal quantum computer), it is a bit more limited. However, as testing has shown, it is definitely quantum and it does what the company making it says it does. Simply speaking, it is what it is.It isn't capable of running Shor's algorithm to crack modern cryptography, but it does do some things better than regular computers and unlike "real" quantum computers it has the advantage of actually existing in a practical implementation. I'm sure uses for it will materialize.
The D-Wave is an “adiabatic” computer that encodes problems into the lowest-energy state of a quantum system. The machine is best suited to solving optimization problems in which several competing criteria must be met, often called “traveling salesman” problems. The computer can test a large number of states in milliseconds to find the best—lowest-temperature—solution.Lockheed is experimenting with the D-Wave for verification and validation of software, a task becoming prohibitively lengthy and costly as systems become more complex. It could also test adaptive, non-deterministic software that cannot be certified by other means, says Ray Johnson, chief technology officer. NASA and Google are looking into machine learning applications. Lockheed, meanwhile, has teamed with the University of Maryland to develop a different type of quantum computing platform that can be used without requiring a deep understanding of its internal workings.“Classical computing can take us only so far,” says Johnson. “Critical systems will become so complex, problems will take too long or become too expensive to solve using even our most powerful supercomputers. We believe that the next computational revolution will stem from applied quantum science.”
Err... Why on Earth does NASA fund research into Quantum Artificial Intelligence??It's fascinating stuff but I don't see the connection to Aeronautics or Space...

A watershed announcement" from Google regarding quantum computers is expected to be made on 8 December, according to a board member of the quantum computing firm D-Wave. Steve Jurvetson gave no other details about what Google is planning, though his comments were related to an image projecting the predicted exponential progress of quantum computing over the next few years.Since they were first theorised by the physicist Richard Feynman in 1982, quantum computers have promised to bring about a new era of ultra-powerful computing. Google has been among the companies pioneering their development, using systems built by the Canadian firm D-Wave to explore the technology's potential for advancing artificial intelligence and machine learning."Stay tuned for what may be a watershed announcement from Google on Dec 8," Jurvetson wrote in a recent comment to the image he posted to Flickr more than three years ago. First spotted by Google news site 9to5Google, Jurveston's remarks come as D-Wave announced that a 1,000+ qubit quantum computer has been sold to national security research institution Los Alamos.
It has been suggested that quantum computers be launched to orbit in order to reduce disturbances which cause decoherence.

The disturbances that are relevant to QC has nothing to do with gravity and can be better controlled here on earth.
If gravity turns out to be a problem, on the margin, for QC, then space might really be the right place for it. But the same was believed about crystals and today, I hear, they are more perfectly produced on Earth than on the ISS.
