Manipulation and Detection of a Trapped Yb+ Ion Hyperfine Qubit
arXiv:0708.0657 · doi:10.1103/PhysRevA.76.052314
Abstract
We demonstrate the use of trapped ytterbium ions as quantum bits for quantum information processing. We implement fast, efficient state preparation and state detection of the first-order magnetic field-insensitive hyperfine levels of 171Yb+, with a measured coherence time of 2.5 seconds. The high efficiency and high fidelity of these operations is accomplished through the stabilization and frequency modulation of relevant laser sources.
