Trapped ions have emerged as a front runner in quantum information processingdue to their identical nature, all-to-all connectivity, and high fidelityquantum operations. As current trapped ion technologies are scaled, it will beimportant to improve the efficiency of loading ions, which is currently theslowest process in operating a trapped ion quantum computer. Here, we comparetwo isotope-selective photoionization schemes for loading $^{138}\mathrm{Ba}^+$ions. We show that a two-step photoionization scheme ending in an autoionizingtransition increases the ion loading rate nearly an order of magnitude comparedto an established technique which does not excite an autoionizing state. Theonly additional technology required to implement the autoionizing transition isa commercial diode laser. Our technique can be extended to all isotopes ofbarium, and autoionizing resonances exist in every species currently used fortrapped ion quantum processing, making this a promising technique todrastically increase the loading rates for all trapped ion computers.
