Formal developments in the context of quantum information theory, together with the superb experimental control on quantum systems attained in the last couple of decades, are giving rise to the appearance of a new field of research and development—quantum technologies—the use of quantum protocols and systems to enhance available technology or even develop totally new devices. Within this field, quantum metrology or quantum sensing focuses in establishing the measurement uncertainties achievable according to quantum mechanics, to devise physical systems able to test them, and to design new measurement devices that translate these findings into practical applications.

Building on the exquisite control and precise detection methods available for trapped atomics ions, we have developed two proposals to use them as quantum probes and control knobs of molecular ions and polar molecules, which I will review in this talk. First, I will present how we extended ideas of quantum logic spectroscopy developed in the context of trapped atomic ions [4] to non-destructive spectroscopy of molecular ions. More recently, we have generalized this approach to ion-neutral species, considering in particular cold polar molecules as a target.
