I don't think the D-Wave article is very good. To pick one choice line, "The term 'Interference' refers to the electrons - which behave as waves inside a quantum waves, interference patterns which give rise to the quantum effects." If someone didn't know what interference was, that sentence certainly wouldn't help them! D-Wave's article also doesn't give a sense of how unsettled this field is, and how many plausible options there are for every element of a quantum computer. I detect the influence of marketing.

The ACM article is much better.
