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…

Quantum state engineering on an optical transition and decoherence in a Paul trap
Ch. Roos, Th. Zeiger, H. Rohde +5
A single Ca+ ion in a Paul trap has been cooled to the ground state of vibration with up to 99.9% probability. Starting from this Fock state |n=0> we have demonstrated coherent qua…
