wow - some serious refrigeration in this system:
That is a doctored picture. Here is the original
when reporters get owned
The chip is a 28-14 nm line width design.
Where did you see that? The dwave link only indicated LSI (~128k junctions) and I thought I recalled my buddy saying dimensions hadn't changed much since we were working on them in the 90's - 4um min geometry back then.
14nm is extreme bleeding edge tech for cmos designed to run around room temperature, used on VLSI processors pushing a billion transistors, 10,000 times more than dwave processor today. Hard to believe they would be remotely close to that in a cryogenic application.
Cool tech, anyhow. Seriously, if you found other good links, please post.

OK … I lied. The newest chip has 0.25 um features, with 128,000 Josephson junctions and 1152 functioning qbits.

There is lots of stuff on their website and in the academic literature. They also been granted over something like 150 US patents.
i was wondering.. he sure sounded prepared….
I'm pretty sure he knew he was going to speaking at that event, in that location, at least a day or two in advance. Good on him for being prepared - even if his preparation only consisted of reading a Wikipedia page. His predecessor wouldn't have bothered to do even that much…

figured as much. the enclosure looks way bigger than it has to be for just the computer bits - lots of room for kegs. tap handles must be behind the glass doors:
