  • Uys, H; Biercuk, MJ; VanDevender, AP; Ospelkaus, C; Meiser, D; Ozeri, R; Bollinger, JJ (American Physical Society, 2010-11)
    The authors present theoretical and experimental studies of the decoherence of hyperfine ground-state superpositions due to elastic Rayleigh scattering of light off resonant with higher lying excited states. They demonstrate ...
  • Uys, H; Biercuk, M; Van Devender, AP; Ospelkaus, C; Meiser, D; Ozeri, R; Bollinger, JJ (SAIP 2010, 2010-09)
    This paper investigates the decoherence of superpositions of hyperfine states of 9Be+ ions due to spontaneous scattering of off-resonant light. It was found that, contrary to conventional wisdom, elastic Raleigh scattering ...
  • Uys, H; Biercuk, M; Britton, JW; Van Devender, AP; Bollinger, JJ (SAIP 2010, 2010-09)
    This article reports on a calibrated measurement of 174 Yoctonewton using a cloud of 60 9 Be+ ion confined in a Penning ion trap. These measurements suggest that ion traps may form the basis of a new class of ultrasensitive ...
  • Uys, H; Biercuk, M; Van Devender, AP; Bollinger, JJ (SAIP 2010, 2010-09)
    The authors study pulse sequences that dynamically decouple 9Be+ ions from their decohering environment. The noise environment the ions see is artificially synthesized to emulate a variety of physical systems. By incorporating ...
  • Uys, H; Amini, JM; Wesenberg, JH; Seidelin, S; Britton, J; Bollinger, JJ; Leibfried, D; Ospelkaus, C; Van Deventer, AP; Wineland, DJ (SAIP 2010, 2010-09)
    The design, fabrication and preliminary testing of a chipscale, multi-zone, surface electrode ion trap is reported. The modular design and fabrication techniques used are anticipated to advance scalability of ion trap ...
  • Sawyer, BC; Britton, JW; Keith, AC; Joseph Wang, CCJ; Freericks, JK; Uys, H; Biercuk, MJ; Bollinger, JJ (American Physical Society, 2012-05)
    We demonstrate spectroscopy and thermometry of individual motional modes in a mesoscopic 2D ion array using entanglement-induced decoherence as a method of transduction. Our system is a 400 µm-diameter planar crystal of ...
