Decoherence due to elastic rayleigh scattering

Author: Uys, H ; Biercuk, MJ ; VanDevender, AP ; Ospelkaus, C ; Meiser, D ; Ozeri, R ; Bollinger, JJ Date: Nov 2010 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 that under ... Read more
Decoherence of superposition states in trapped ions

Author: Uys, H ; Biercuk, M ; Van Devender, AP ; Ospelkaus, C ; Meiser, D ; Ozeri, R ; Bollinger, JJ Date: Sep 2010 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 can have major ... Read more
Evolution of optical vortex distributions in stochastic vortex fields

Author: Roux, FS Date: Jan 2011 Stochastic vortex fields are found in laser speckle, in scintillated beams propagating through a turbulent atmosphere, in images of holograms produced by Iterative Fourier Transform methods and in the beams produced by certain diffractive ... Read more
Evolution of orbital angular momentum entangled bi-photon, propagating through a turbulent atmosphere

Author: Roux, FS Date: Jan 2011 Orbital angular momentum (OAM) entangled bi-photons are a resource for the higher dimensional implementation of quantum cryptography, which allows secure communication over various channels. In the case where free-space is used as communication ... Read more
