Nevertheless\, the interf ace of gravity and quantum theory can become relevant even at low energies\ , with experimentally accessible signatures.\n\nIn this talk I will first g ive a brief overview of some results in this field from our group\, discuss ing how post-Newtonian corrections can affect quantum interferometry with c locks. I will then focus on the possibility to detect single gravitons. We demonstrate how signatures of single-graviton-exchange can be observed in l aboratory experiments. We show that for massive quantum acoustic resonators \, absorption of single gravitons from background gravitational waves can b e resolved through continuous quantum sensing of quantum jumps. Our results show that single graviton signatures are within reach of experiments. In a nalogy to the discovery of the photo-electric effect for photons\, I will d iscuss how such signatures can provide the first (weak) experimental eviden ce of the quantization of gravity.
