That has to be one of the most tortured opening metaphors I've ever seen in a tech news story. Could they really not come up with an analogy more elegant than, "This building over here is pretty big, but this building is REALLY BIG!!!!"?
This is a vast oversimplification of quantum computing. Also, I think its pretty optimistic on the timeline of quantum computing. If you want to read more detailed content see Scott Aaronson's blog <a href="http://www.scottaaronson.com/blog/" rel="nofollow">http://www.scottaaronson.com/blog/</a>
>some problems in mathematics will remain beyond the limits of quantum computing<p>I don't think it's surprising that quantum computers, by themselves, will not be able to solve mathematical problems. Problem solving is not a feature of hardware per se, it is done by humans. Perhaps one day by AIs, too, if we can discover how to program them.<p>Two tantalising potential benefits of Quantum Computers:<p>(1) the ability to model all kinds of matter efficiently at the molecular level which will spur the development of nanotech<p>(2) people will ask 'Where are these humongous computations being performed?' and then embrace the 'many worlds interpretation' of quantum mechanics, which will in turn create further scientific and philosophical progress
Articles with titles that could've been true (but weren't) for the last decade are much like articles with titles consisting of questions to which the answer is no.

"Quantum computing could be five years away"<p>They said this fifteen years ago on a radio broadcast. I was sitting there. I heard it.<p>Now, for the last time, <i>where</i> is my <i>jetpack</i>?
