Search for correlation effects in linear chains of trapped Ca+ ions

Abstract:

We report a precise search for correlation effects in linear chains of 2 and 3 trapped Ca+ ions. Unexplained correlations in photon emission times within a linear chain of trapped ions have been reported, which, if genuine, cast doubt on the potential of an ion trap to realize quantum information processing. We observe quantum jumps from the met astable 3d2 D5/2 level for several hours, searching for correlations between the decay times of the different ions. We find no evidence for correlati...
