Extended Data Table 1 Comparison with other matter-wave interference experiments

  1. We compare the wave packet separation Δz, the duration T between the beam splitter and mirror sequences, and the mass m to those of a sodium interferometer from 199240, a caesium interferometer from 200137, a neutron interferometer from 200241, a C70 molecular interferometer from 200242, a caesium interferometer from 200938, a caesium interferometer from 201239, a C284H190F320N4S12 molecular interferometer from 201343, and a rubidium interferometer from 201325. Additionally, we compare the factor mΔzT/h- , which is directly related to the acceleration sensitivity (see the discussion of acceleration sensitivity in the main text). The wave-packet separation in our experiment is nearly an order of magnitude larger than the next largest value (from a neutron interferometer), and the duration in our experiment is more than four orders of magnitude longer than in the neutron interferometer with a nearly hundred times larger mass.
