    "abstract": "In papers on primary state diffusion (Percival 1994, 1995), numerical\nestimates suggested that fluctuations in the space-time metric on the scale of\nthe Planck time (10^-44s) could be detected using atom interferometers. In this\npaper we first specify a stochastic metric obtained from fluctuations that\npropagate with the velocity of light, and then develop the non-Markovian\nquantum state diffusion theory required to estimate the resulting decoherence\neffects on a model matter interferometer. Both commuting and non-commuting\nfluctuations are considered. The effects of the latter are so large that if\nthey applied to some real atom interferometry experiments they would have\nsuppressed the observed interference. The model is too crude to conclude that\nsuch fluctuations do not exist, but it does demonstrate that the small\nnumerical value of the Planck time does not alone prevent experimental access\nto Planck-scale phenomena in the laboratory.",
