ResumenIn the last years, a lot of progress has been made in trapping and cooling of atomic ions. Very recently, trapping and cooling to the mK regime has been extended to molecular ions in well defined internal states [1,2], opening a new window for high precision spectroscopy of molecular species. In these experiments, the detection of the quantum state of 14N2+ molecular ions was done by laser-induced charge transfer with Ar, an inherently destructive process. Here, we propose a fast, efficient and accurate spectroscopic method for molecular ions that imple- ments quantum logic schemes between an atomic ion and the molecular ion of interest. Our proposal relies on a hybrid manipulation of the system, using optical forces for the atomic ion, and either opti- cal forces or magnetic field gradients for the molecular ion. The gate operates in times ranging from 10 ¿s to 1 ms, and enables a number of applications. The most immediate one is the determination of magnetic moments or Zeeman shifts of ions such as N2+ or O2+, for spectroscopic purposes, much in the line of the experiments by Schmidt and coworkers [3]. In this way, we set a starting point towards novel methods of high-precision spectroscopy of molecules and molecular ions of interest in a variety of fields, from astrophysics to physical chemistry to metrology.
