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…
Design and characterization of a cryogenic vacuum chamber for ion trapping experiments
D. M. Hartsell, J. M. Gray, C. M. Shappert +5
We present the design and characterization of a cryogenic vacuum chamber incorporating mechanical isolation from vibrations, a high numerical-aperture in-vacuum imaging objective,…
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…
Rapid Exchange Cooling with Trapped Ions
Spencer D. Fallek, Vikram S. Sandhu, Ryan A. McGill +4
The trapped-ion quantum charge-coupled device (QCCD) architecture is a leading candidate for advanced quantum information processing. In current QCCD implementations, imperfect ion…
Universal Control of Ion Qubits in a Scalable Microfabricated Planar Trap
Creston D. Herold, Spencer D. Fallek, J. True Merrill +4
We demonstrate universal quantum control over chains of ions in a surface-electrode ion trap, including all the fundamental operations necessary to perform algorithms in a one-dime…
In-Vacuum Active Electronics for Microfabricated Ion Traps
Nicholas D. Guise, Spencer D. Fallek, Harley Hayden +10
The advent of microfabricated ion traps for the quantum information community has allowed research groups to build traps that incorporate an unprecedented number of trapping zones.…
A 750 mW, continuous-wave, solid-state laser source at 313 nm for cooling and manipulating trapped 9Be+ ions
Andrew. C. Wilson, Christian Ospelkaus, Aaron. P. VanDevender +4
We present a solid-state laser system that generates 750 mW of continuous-wave single-frequency output at 313 nm. Sum-frequency generation with fiber lasers at 1550 nm and 1051 nm…
Single-qubit-gate error below 10^-4 in a trapped ion
K. R. Brown, A. C. Wilson, Y. Colombe +5
With a 9Be+ trapped-ion hyperfine-states qubit, we demonstrate an error probability per randomized single-qubit gate of 2.0(2) x 10^-5, below the threshold estimate of 10^-4 common…
