Nature: Single-atom bit forms smallest memory in the world
Date:11/18/2013

This news release is available in German.

One atom equals one bit: According to this design principle, we would like to construct magnetic data memories in the future. Presently, a compound of several million atoms is needed to stabilize a magnetic bit in a way that hard disk data are secure for several years. However, researchers from KIT have just made a big step towards a single-atom bit: They fixed a single atom on a surface such that the magnetic spin remained stable for ten minutes. Their report is published in the current issue of the Nature magazine (DOI 10.1038/nature12759).

"Often, a single atom fixed to a substrate is so sensitive that its magnetic orientation is stable for fractions of a microsecond (200 nanoseconds) only," Wulf Wulfhekel from Karlsruhe Institute of Technology (KIT) explains. Together with colleagues from Halle, he has now succeeded in extending this period by a factor of about a billion to several minutes. "This does not only open up the possibility of designing more compact computer memories, but could also be the basis for the setup of quantum computers," Wulfhekel says. Quantum computers are based on quantum physics properties of atomic systems. In theory at least, their speed might exceed that of classical computers by several factors.

In their experiment, the researchers placed a single holmium atom onto a platinum substrate. At temperatures close to absolute zero, i.e. at about 1 degree Kelvin, they measured the magnetic orientation of the atom using the fine tip of a scanning tunneling microscope. The magnetic spin changed after about 10 minutes only. "Hence, the magnetic spin of the system is stable for a period that is about a billion times longer than that of comparable atomic systems," Wulfhekel emphasizes. For
