Further, longer lifetime species with cycling transitions may also be useful for experi-ments using quantum logic spectroscopy. Here, the cycling transition can be used to optically pump the molecular internal states to greatly improve the rate of the heralded state preparation and measurement used in quantum logic spectroscopy. The cations presented in this manuscript show properties that make them promising candidates for use in these applications. The range of described properties allows one to select the cations that match the best desired experimental requirements for a particular application.
