As we are not going to see scanning tunnelling microscopes included in our home computers anytime soon this experiment is simply proof of the concept that data can be stored on a single atom. That does not make it any less interesting for those fascinated by atomic storage techniques. A single atom of holmium can be made to spin either up or down, signifying either a 0 or 1, and that spin state can be 'read' by measuring the vibration of a single iron atom located close by. The holmium atoms used for storage can be separated by a mere nanometer without interfering with the spin of its neighbours. The spin state only lasts a few hours but shows that this could someday be a viable storage technology. You can read more at nanotechweb, who also have links to the Nature article.
"Information has been stored in a single atom for the first time. The nascent binary memory was created by Andreas Heinrich at the Institute of Basic Science in South Korea and an international team."
