David Wineland and Chris Monroe at the National Institute of Standards
and Technology in Boulder, CO have "managed to coax an atom to exist in
two places at once". They used lasers and a magnet to push the spin-down
version of a beryllium atom ten atom-widths away from its spin-down self.
It's fragile, but it's a start. I, for one, am excited. I find this at
least as significant to nanotech as the atom laser.
