Control Freaks! Making Quantum Systems Do Our Bidding

In the 20th century we viewed quantum mechanics as a kind of nagging authority.  You can't know position and momentum at the same time.  You can't measure a system without disturbing it.  You can't predict the outcome of an experiment -- it's random.  As the 21st century approached, this understanding was turned on its head.  Quantum theory is not a paler version of Newton's deterministic mechanistic world, it is a richer world that enables information processing tasks that are fundamentally more powerful than those which can be accomplished in the classical world.  We just need to control quantum systems to make them do what we want.  In this colloquium I will describe some process in this direction as we tame quantum information encoded in ultracold atoms -- the coldest stuff in the universe.
