We have pursued two avenues in an attempt to address this problem. First, we will discuss how optical frequency combs may be employed to ease the creation of short-wavelength light. We find that, when illuminated by a comb, trapped ions can behave as a phonon laser whose gain saturation protects them from being boiled out of the trap by the hundreds of blue-detuned comb teeth present. Second, in collaboration with Eric Hudson's group at UCLA, we describe work with barium ions, the species with the longest-wavelength transitions among the obvious choices. We discuss why creating a particular radioactive isotope endows Ba+ with the atomic structure advantages of more-difficult species and position it as a flexible, easy to use, all purpose qubit.
