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…
Optimized Noise Filtration through Dynamical Decoupling
Hermann Uys, Michael J. Biercuk, John J. Bollinger
One approach to maintaining phase coherence of qubits through dynamical decoupling consists of applying a sequence of Hahn spin-echo pulses. Recent studies have shown that, in cert…
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…
