Abstract

Recently developed techniques for quantum computation using trapped ions allow unprecedented coherent control of the internal and external states of single atoms. Here we report how these techniques can be employed to perform precision spectroscopy of atomic and molecular ions that have no accessible transition for laser cooling and detection. Furthermore, we discuss how quantum logic can be used to cool molecules to their rotational and vibrational ground state by avoiding detrimental spontaneous emission of photons from the molecule.
