A1 - Wunderlich, Chr T1 - Individual addressing of trapped ions and coupling of motional and spin states using RF radiation T2 - Physical review letters N2 - Individual electrodynamically trapped and laser cooled ions are addressed in frequency space using radio-frequency radiation in the presence of a static magnetic field gradient. In addition, an interaction between motional and spin states induced by an rf field is demonstrated employing rf optical double resonance spectroscopy. These are two essential experimental steps towards realizing a novel concept for implementing quantum simulations and quantum computing with trapped ions.
