Extended Data Fig. 4: Atom interferometer decoherence rate as a function of scatter.
From: Measuring gravitational attraction with a lattice atom interferometer
Projected lattice atom interferometer decoherence (contrast decay κ) versus level of scatter of the surface of the mirror. The atoms are held 100 μm from the mirror at three different offset distances between the atom cloud and scatterer positions: 0, 0.3 and 1.0 mm. We observe marked decoherence when the scattered intensity is more than 100 ppm of the incident laser power.
