Surface-electrode Ion trap with integrated light source
Applied Physics Letters, 2011Co-Authors: Peter F. Herskind, Isaac L. ChuangAbstract:An atomic Ion is trapped at the tip of a single-mode optical fiber in a cryogenic (8 K) surface-electrode Ion trap. The fiber serves as an integrated source of laser light, which drives the quadrupole qubit transitIon of S88r+. Through in situ translatIon of the nodal point of the trapping field, the Gaussian beam profile of the fiber output is imaged, and the fiber-Ion Displacement, in units of the mode waist at the Ion, is optimized to within 0.13±0.10 of the mode center despite an initial offset of 3.30±0.10. Fiber-induced charging by 125 μW of 674 nm light is observed to be ∼10 V/m at an Ion height of 670 μm, with charging and discharging time constants of 1.6±0.3 s and 4.7±0.6 s, respectively. This work is of importance to large-scale, Ion-based quantum informatIon processing, where optics integratIon in surface-electrode designs may be a crucial enabling technology.

high temperature x ray study of the cubic tetragonal diffusIonless phase transitIon in the zro2 ero1 5system ii temperature dependences of oxygen Ion Displacement and lattice parameter of compositIonally homogeneous 12 mol ero1 5 zro2
Journal of the American Ceramic Society, 1993Co-Authors: Masatomo Yashima, Nobuo Ishizawa, Masahiro YoshimuraAbstract:The tetragonal-to-cubic phase transitIon of rapidly quenched 12 mol% ErO1.5─ZrO2 was investigated in situ using high-temperature X-ray diffractIon. Rapid quenching of the melt yielded a small oxygen Ion Displacement and a small tetragonality, axial ratio c/a. Although the tetragonality of the as-quenched specimen increased with temperature up to about 1000°C, it became independent of temperature on cooling to room temperature from about 1000°C and reheating up to 1000°C. The tetragonality decreased continuously with temperature above 1000°C and became unity at about 1400°C. The atomic coordinatIon z for the oxygen Ion, which expresses the Displacement from its ideal site in the fluorite-type structure, increased with temperature and became 1/4 at about 1400°C. The tetragonality increased with annealing time through a thermal activatIon, which could explain the compositIonal dependence of the tetragonality in rapidly quenched ZrO2─RO1.5 samples (R = rare earths).
