I will give a brief overview of measurement and control, and ground state cooling strategies for quantum systems across different scales. I will then discuss what such capabilities for massive quantum systems may enable us to do: the inference of quantized energy exchanges between gravitational waves and matter at the level of a single graviton. The quantization of gravity is widely believed to result in gravitons -- particles of discrete energy that form gravitational waves. However, their detection has so far been considered impossible. I will show that stimulated and spontaneous single-graviton processes can become relevant for massive quantum acoustic resonators. I will discuss how this allows us to infer quantized energy exchanges between gravitational waves and matter at the level of a single graviton. In analogy to the discovery of the photo-electric effect for photons, such signatures can provide the first experimental clue of the quantization of gravity.
