• Abstract: We present a practical scheme for the efficient preparation of laser-cooled $^{43}$Ca$^+$ ions in an ion trap. Our approach integrates two well-established methods: isotope-selective photoionization and isotope-specific parametric excitation. Drawing inspiration from the individual merits of each method, we have successfully integrated these techniques to prepare extended chains of $^{43}$Ca$^+$ ions, overcoming the challenge posed by their low natural abundance of 0.135\% in a natural source. Furthermore, we explore the subtleties of our scheme, focusing on the influence of different factors on the purification process. Our investigation contributes to a broader understanding of the technique and highlights the adaptability of established methods in addressing specific isotopic challenges.

  Fluorescence collection from individual emitters plays a key role in state detection and remote entanglement generation. Planar photonics have been demonstrated for robust and scalable addressing of trapped-ion systems. We show that far-field photon collection efficiency can be simply expressed in terms of the fields associated with the collection optic at the emitter position alone.

  We introduce a machine learning approach to determine the transition dynamics of silicon atoms on a single layer of carbon atoms.

These learned transition dynamics are then leveraged to guide a single silicon atom throughout the lattice to pre-determined target destinations.

  We provide a framework that allows different simulation methods to be hybridized and thereby improve performance for interaction picture simulations. Physical applications of these hybridized methods yield a gate complexity scaling as $log2 Lambda$ in the electric cutoff. For the general problem of Hamiltonian simulation subject to dynamical constraints, these methods yield a query complexity independent of the penalty parameter $lambda$ used to impose an energy cost.
