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…
Demonstration of a scalable, multiplexed ion trap for quantum information processing
D. R. Leibrandt, J. Labaziewicz, R. J. Clark +14
A scalable, multiplexed ion trap for quantum information processing is fabricated and tested. The trap design and fabrication process are optimized for scalability to small trap si…
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…
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…
