Dual-Platform Precision Measurement of the to -Factor Ratio in
Brian J. McMahon, Vikram S. Sandhu, John M. Gray +3
We report precision measurements of the ratio of Landé factors between the and states of a single trapped ion. The measurements are…
Efficient Three-Dimensional Sub-Doppler Cooling of Ca in a Penning Trap
Brian J. McMahon, Brian C. Sawyer
We demonstrate efficient sub-Doppler laser cooling of the three eigenmodes of a Ca ion confined in a compact Penning trap operating with a magnetic field of 0.91 T. Usin…
Exactly-solved model of light-scattering errors in quantum simulations with metastable trapped-ion qubits
Phillip C. Lotshaw, Brian C. Sawyer, Creston D. Herold +1
We analytically solve a model for light scattering in Ising dynamics of metastable atomic qubits, generalizing the approach of Foss-Feig {\it et al.}~[Phys.~Rev.~A {\bf 87}, 042101…
Absorption Spectroscopy of Ca Atomic Beams Produced via Pulsed Laser Ablation: A Quantitative Comparison of Ca and CaTiO Targets
Kevin D. Battles, Brian J. McMahon, Brian C. Sawyer
Pulsed laser ablation is an increasingly prevalent method for fast ion trap loading of various species, however characteristics of the ablation target source material can affect th…
Individual-Ion Addressing and Readout in a Penning Trap
Brian J. McMahon, Kenton R. Brown, Creston D. Herold +1
We implement individual addressing and readout of ions in a rigidly rotating planar crystal in a compact, permanent magnet Penning trap. The crystal of Ca is trapped and…
