    "abstract": "The coherence of a hyperfine-state superposition of a trapped $^{9}$Be$^+$\nion in the presence of off-resonant light is experimentally studied. It is\nshown that Rayleigh elastic scattering of photons that does not change state\npopulations also does not affect coherence. Coherence times exceeding the\naverage scattering time of 19 photons are observed. This result implies that,\nwith sufficient control over its parameters, laser light can be used to\nmanipulate hyperfine-state superpositions with very little decoherence.",
