The QGate team has realized the most fundamental implementation of an optical quantum memory: Arbitrary polarization states of light can be mapped into and out of a single atom trapped inside an optical cavity, achieving an average fidelity of 93% and storage times of more than 180µs. More information for the general audience can be found in our press release.

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.
