Hyperfine-mediated electric quadrupole shifts in Al and In ion clocks
K. Beloy, D. R. Leibrandt, W. M. Itano
We evaluate the electric quadrupole moments of the and clock states of Al and In. To capture all dominant contributions, our analysis…
Diamagnetic correction to the Be ground-state hyperfine constant
N. Shiga, W. M. Itano, J. J. Bollinger
We report an experimental determination of the diamagnetic correction to the Be ground state hyperfine constant . We measured = Hz at a magn…
High-fidelity quantum control using ion crystals in a Penning trap
Michael J. Biercuk, Hermann Uys, Aaron P. VanDevender +3
We discuss the use of two-dimensional Be ion crystals for experimental tests of quantum control techniques. Our primary qubit is the 124 GHz ground-state electron spin…
Experimental Uhrig Dynamical Decoupling using Trapped Ions
Michael J. Biercuk, Hermann Uys, Aaron P. VanDevender +3
We present a detailed experimental study of the Uhrig Dynamical Decoupling (UDD) sequence in a variety of noise environments. Our qubit system consists of a crystalline array of $^…
Optimized Dynamical Decoupling in a Model Quantum Memory
Michael J. Biercuk, Hermann Uys, Aaron P. VanDevender +3
We present experimental measurements on a model quantum system that demonstrate our ability to dramatically suppress qubit error rates by the application of optimized dynamical dec…
Simplified motional heating rate measurements of trapped ions
R. J. Epstein, S. Seidelin, D. Leibfried +13
We have measured motional heating rates of trapped atomic ions, a factor that can influence multi-ion quantum logic gate fidelities. Two simplified techniques were developed for th…
