  • Sastrawan, J; Jones, C; Akhalwaya, I; Uys, H; Biercuk, MJ (American Physical Society, 2016-08)
    We introduce concepts from optimal estimation to the stabilization of precision frequency standards limited by noisy local oscillators. We develop a theoretical framework casting various measures for frequency standard ...
  • Green, TJ; Sastrawan, J; Uys, H; Biercuk, MJ (Institute of Physics, 2013-09)
    We address the problem of deriving analytic expressions for calculating universal decoherence-induced errors in qubits undergoing arbitrary, unitary, time-dependent quantum control protocols. We show that the fidelity of ...
  • 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 ...
  • Britton, JW; Sawyer, BC; Keith, AC; Wang, CCJ; Freericks, JK; Uys, H; Biercuk, MJ; Bollinge, JJ (Macmillan Publishers, 2012-04)
    The presence of long-range quantum spin correlations underlies a variety of physical phenomena in condensed-matter systems, potentially including high-temperature superconductivity. However, many properties of exotic, ...
  • Soare, A; Ball, H; Hayes, D; Zhen, X; Jarratt, MC; Sastrawan, J; Uys, H; Biercuk, MJ (American Physical Society, 2014-04)
    We develop and demonstrate a technique to engineer universal unitary baths in quantum systems. Using the correspondence between unitary decoherence due to ambient environmental noise and errors in a control system for ...
  • Green, T; Uys, H; Biercuk, MJ (American Physical Society, 2012-07)
    Treating the effects of a time-dependent classical dephasing environment during quantum logic operations poses a theoretical challenge, as the application of noncommuting control operations gives rise to both dephasing and ...
  • 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 ...
