Randomized Benchmarking of Quantum Gates
E. Knill, D. Leibfried, R. Reichle +7
A key requirement for scalable quantum computing is that elementary quantum gates can be implemented with sufficiently low error. One method for determining the error behavior of a…
Errors in trapped-ion quantum gates due to spontaneous photon scattering
R. Ozeri, W. M. Itano, R. B. Blakestad +9
We analyze the error in trapped-ion, hyperfine qubit, quantum gates due to spontaneous scattering of photons from the gate laser beams. We investigate single-qubit rotations that a…
Transport dynamics of single ions in segmented microstructured Paul trap arrays
R. Reichle, D. Leibfried, R. B. Blakestad +7
It was recently proposed to use small groups of trapped ions as qubit carriers in miniaturized electrode arrays that comprise a large number of individual trapping zones, between w…
A microfabricated surface-electrode ion trap in silicon
J. Britton, D. Leibfried, J. Beall +13
The prospect of building a quantum information processor underlies many recent advances ion trap fabrication techniques. Potentially, a quantum computer could be constructed from a…
A microfabricated surface-electrode ion trap for scalable quantum information processing
S. Seidelin, J. Chiaverini, R. Reichle +12
We demonstrate confinement of individual atomic ions in a radio-frequency Paul trap with a novel geometry where the electrodes are located in a single plane and the ions confined a…
Long-lived qubit memory using atomic ions
C. Langer, R. Ozeri, J. D. Jost +13
We demonstrate experimentally a robust quantum memory using a magnetic-field-independent hyperfine transition in 9Be+ atomic ion qubits at a magnetic field B ~= 0.01194 T. We obser…
