Abstract Atom interferometry for extended drift times promise a major leap in improving precision and accuracy of matter-wave sensors. When taking advantage of the unique space environment for example, fundamental tests challenging the state-of-the-art can be performed using quantum gases systems. The use of cold atoms as a source for such sensors poses however intrinsic challenges mainly linked to the samples size and mixture dynamics in case of dual-atomic tests. In this context, the design of the input states with well-defined initial conditions is required. In this talk, I will report about quantum state engineering methods used to precisely and efficiently control the positions, velocities, expansion rates and squeezing of atomic ensembles in state-of-the-art quantum gas experiments on ground and in space.
