First quantum gates in silicon

Australian researchers have figured out how to make a quantum gate on a
silicon chip.  This is interesting work, because we've spent a *lot* of
money learning how to etch silicon.  Being able to build quantum gates
on the same material that our current systems use is really important
from an engineering perspective.

So far they've only been able to build a two-qubit chip.  This means
there's absolutely nothing to panic over.  Still, it's fascinating news.
 We live in interesting times.  :)
