This is a really misleading article. What they're referring to is placing atoms (and molecules) into states of superposition where the state can be represented as 1/sqrt(2)|left> + 1/sqrt(2)|right>. This is an important first step towards quantum computers--being able to construct entangled systems of many q-bits, but this article is really quite poor in it's description. If you're really interested in this sort of stuff, I'd suggest reading Charles Seife's book entitled _Decoding the Universe_. It's about information theory and discusses quantum computing to a certain extent. I've also heard Seth Lloyd's book Programming the Universe is very good, but I have not read it.
