By combining the technologies of ion trapping and cavity QED, we have achieved deterministic coupling of single ions to an optical field. By Doppler cooling, the spread of the ion's wavepacket was reduced to 42 nm, corresponding to Lamb-Dicke localization. As an application, we have measured the three-dimensional structure of cavity eigenmodes with sub-wavelength precision. The setup presented is suited for the controlled coherent processing of atomic and photonic quantum information. Examples include the triggered generation of single photons and two-ion quantum gates.

Notes

The paper introduces the technique of ion-trap cavity-QED. M.K. was the principal scientist performing the largest share of experimental work and constructing important components. W.L. was the leader of the team. The remaining authors' contributions were limited to parts of the laser system (K.H., B.L.) and financial support (H.W).
