If you drill around, there's a fair bit of criticism / scepticism on the internet about the company and their claims. Here's one:
"They won't tell anyone how the machine works and so, even in principle, no one knows if it is possible that it might actually be a quantum computer." There are plenty of other examples out there, some snarkier than others.
Anyway, D-Wave recently tried to answer their critics (and, truth be known, shore up their share values, but hey...) - though no one's really any much the wiser.
Be warned: you are about to encounter such brain-mangling concepts as Gate Model Vs Adiabatic Quantum Computing, quantum annealing, etc. Even though this article is written in English, have some paracetamol handy.
"In 2009, we did some work with Google to develop a car classifying [system]. It did object identification in image search. The idea was to be able to use our 128 qubit processor to train an algorithm to be able to identify if a car was in a picture or not. These kinds of questions seem a bit odd to us, because as humans it's very easy to determine if there's a car in a picture. But a machine looks at it in terms of pixels rather than objects. A lot of machine learning is how do we get machines to think of pictures as the objects instead of the raw data."
(Google, it has to be said, are pretty, er, 'into' object-within-image recognition technologies...)
My favourite bit, TBH, is the guy in the comments-box who says that Quantum Computing is roughly at the same stage as Classical Computing was with the ENIAC computer in 1946.
