Yes, their demonstration worked on tuesday. It played sudoku, matched molecules and did some simple calculations. At such a low qubit number, its not very powerful. Still, its working and that counds for ALOT. When you stack a few thousand qubits youve got yourself some seriously power. Check out their news on the D-Wave blog
And for some video on the actual test which was oddly enough, done remotely, check it out on google videos.
The remote access does show some concern about whether or not its authentic, but…if you watch the video, the computers pretty slow. A company and technology worth looking into 🙂
