Experiments towards quantum information with trapped Calcium ions
D. Leibfried, C. Roos, P. Barton +8
Ground state cooling and coherent manipulation of ions in an rf-(Paul) trap is the prerequisite for quantum information experiments with trapped ions. With resolved sideband coolin…

Sympathetic ground state cooling and coherent manipulation with two-ion-crystals
H. Rohde, S. T. Gulde, C. F. Roos +5
We have cooled a two-ion-crystal to the ground state of its collective modes of motion. Laser cooling, more specific resolved sideband cooling is performed sympathetically by illum…

Ground state cooling, quantum state engineering and study of decoherence of ions in Paul traps
F. Schmidt-Kaler, Ch. Roos, H. C. Naegerl +12
We investigate single ions of in Paul traps for quantum information processing. Superpositions of the S electronic ground state and the metastable D sta…
