Abstract: We consider the quantization of linearized Einstein equations on 4-dimensional asymptotically flat spacetimes. We prove the existence of fully gauge invariant Hadamard states in the harmonic gauge for any Einstein metric asymptotic to the Minkowski metric in a conic neighborhood of spatial infinity.
