In an experiment published today in Nature, IBM researchers have managed to read and write data to a single atom. A previous atomic storage technique, as mentioned by TechCrunch, doesn't actually store data in the atom, but moves them around to form readable patterns. "This means that imbuing individual atoms with a 0 or 1 is the next major step forward and the next major barrier in storing data digitally, both increasing capacity by orders of magnitude and presenting a brand new challenge to engineers and physicists," reports TechCrunch. From the report:
It works like this: A single Holmium atom (a large one with many unpaired electrons) is set on a bed of magnesium oxide. In this configuration, the atom has what's called magnetic bistability: It has two stable magnetic states with different spins (just go with it). The researchers use a scanning tunneling microscope (also invented at ...
