    "abstract": "We analyze the quantum fluctuations of vacuum stress tensors and spacetime\ncurvatures, using the framework of linear response theory which connects these\nfluctuations to dissipation mechanisms arising when stress tensors and\nspacetime metric are coupled. Vacuum fluctuations of spacetime curvatures are\nshown to be a sum of two contributions at lowest orders; the first one\ncorresponds to vacuum gravitational waves and is restricted to light-like\nwavevectors and vanishing Einstein curvature, while the second one arises from\ngravity of vacuum stress tensors. From these fluctuations, we deduce noise\nspectra for geodesic deviations registered by probe fields which determine\nultimate limits in length or time measurements. In particular, a relation\nbetween noise spectra characterizing spacetime fluctuations and the number of\nmassless neutrino fields is obtained.",
