"A single-atom quantum memory" by Holger Specht et al. has been published in Nature. 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.

He says: "A subtle quantum-interference effect has been used to control the optical response of a single atom confined in a cavity. It could offer a means to develop logic gates for an optical quantum computer."

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.
