Multi-loop matter-wave interferometers are essential in quantum sensing to measure the derivatives of physical quantities in time or space. Because multi-loop interferometers require multiple reflections, imperfections of the matter-wave mirrors crea

Interleaved atom interferometry brings high sensitivity and temporal resolution to cold-atom inertial sensors.
Cold-atom inertial sensors target several applications in navigation, geoscience, and tests of fundamental physics. Achieving high sam

We study theoretically and experimentally the influence of temporally shaping the light pulses in an atom interferometer, with a focus on the phase response of the interferometer. We show that smooth light pulse shapes allow rejecting high frequency

Our cold-atom gyroscope is based on a four-pulse configuration with a very large Sagnac area. Its short-term stability is limited by aliasing effects of the inertial forces (acceleration and rotation). We will show how continuous measurements and rea
