Matter-wave interferometry and spectroscopy of optomechanical resonators
offer complementary advantages. Interferometry with cold atoms is employed for
accurate and long-term stable measurements, yet it is challenged by its dynamic
range and cyclic acquisition. Spectroscopy of optomechanical resonators
features continuous signals with large dynamic range, however it is generally
subject to drifts. In this work, we combine the advantages of both devices.
Measuring the motion of a mirror and matter waves interferometrically with
respect to a joint reference allows us to operate an atomic gravimeter in a
seismically noisy environment otherwise inhibiting readout of its phase. Our
method is applicable to a variety of quantum sensors and shows large potential
for improvements of both elements by quantum engineering.
