If you have a question about this talk, please contact Vincent Boyer. Note unusual time Penrose and, independently, Diosi, have suggested that gravitational interactions in quantum dynamics should lead to an intrinsic decoherence. I will review their arguments and show how they can impact future experiments in optomechanics. I will also show that these models of gravitational decoherence can be obtained by treating the gravitational interaction between two mechanical resonators as a classical measurement channel. The resulting decoherence model implies that the classically mediated gravitational interaction between two gravitationally coupled resonators cannot create entanglement. The gravitational decoherence rate ( and the complementary heating rate) is of the order of the gravitationally induced normal mode splitting of the two resonators.
