Detecting single gravitons with quantum sensing. [PDF]
Nat Commun, 2023 The quantization of gravity is widely believed to result in gravitons – particles of discrete energy that form gravitational waves. But their detection has so far been considered impossible. Here we show that signatures of single graviton exchange can be
