Abstract

—We report on the current performance of our atom interferometry gravity gradiometer. After careful elimination of the main sources of fluctuations and biases in the atom interferometer, we achieve a sensitivity of 3×10−9 g per second to differential gravity; by modulating the position of a set of source masses, we achieve a relative statistical uncertainty of 1.1×10−4 to the gravitational constant G.
