Abstract

The coherence of hyperfine-state superpositions of a trapped 9Be+ ion is experimentally studied in the presence of off-resonant light. It is shown that Rayleigh elastic scattering of photons that does not change state populations also does not affect coherence. Coherence times exceeding the average scattering time of 19 photons are observed. This result implies that, with sufficient control over its parameters, laser light can be used to manipulate hyperfine-state superpositions with very little decoherence.
