The theory of quantum mechanics predicts bizarre phenomena, that defy common sense. Its only mystery, according to Richard Feynman, lies in the double-slit experiment.Nowadays, we have experimented the interference of matter waves with several microscopic systems. However, extending these experiments to macroscopic object remains an exceptionally daunting task. In this talk, I will present some recent progress towards this long-standing goal. We levitate a piece of solid and control its motion at the level of single quanta. Furthermore, by controlling the potential landscape, we delocalize the motion of such an object to a length greater than the zero-point fluctuations. I will give an overview of the next steps and future challenges.
