March 2010: MPQ made up of a single atom! The QGate team can position their single atom with micrometer precision inside the cavity. Adding storage times of 70 seconds, fun and creativity, the MPQ logo can be "written" by recording the fluorescence of a single atom. Vertical axis: position of the atom. Horizontal axis: time.

Real-time feedback — the use of continuously updated information about a system to control its evolution — has been demonstrated by Alexander Kubanek et al in Nature to control the motion of a single atom in an optical trap. In an impressive extension of this technique to the edge of the quantum realm, the detection of just a few photons is sufficient to keep the atom under control.
