Dual-Platform Precision Measurement of the to -Factor Ratio in
Brian J. McMahon, Vikram S. Sandhu, John M. Gray +5
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…
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…
Characterization of Fast Ion Transport via Position-Dependent Optical Deshelving
Craig R. Clark, Creston D. Herold, J. True Merrill +11
Ion transport is an essential operation in some models of quantum information processing, where fast ion shuttling with minimal motional excitation is necessary for efficient, high…
Second-Scale Spin Coherence in a Compact Penning Trap
Brian J. McMahon, Brian C. Sawyer
We report microwave spectroscopy of co-trapped and within a compact permanent-magnet-based Penning ion trap. The trap is constructed with a recon…
Doppler Cooled Ions in a Compact, Reconfigurable Penning Trap
Brian J. McMahon, Curtis Volin, Wade G. Rellergert +1
We report the design and experimental demonstration of a compact, reconfigurable Penning ion trap constructed with rare-earth permanent magnets placed outside of a trap vacuum encl…
Testing the Robustness of Robust Phase Estimation
Adam M. Meier, Karl A. Burkhardt, Brian J. McMahon +1
The Robust Phase Estimation (RPE) protocol was designed to be an efficient and robust way to calibrate quantum operations. The robustness of RPE refers to its ability to estimate a…
Transport Implementation of the Bernstein-Vazirani Algorithm with Ion Qubits
Spencer Fallek, Creston Herold, Brian McMahon +3
Using trapped ion quantum bits in a scalable microfabricated surface trap, we perform the Bernstein-Vazirani algorithm. Our architecture relies upon ion transport and can readily b…
