Quantum coherence of Gaussian states in curved spacetime

We study quantum coherence of two-mode Gaussian states in the background of an asymptotically flat black hole. We find that quantum coherence between mode A observed by an inertial observer Alice and mode B observed by an accelerated Bob who hovers near the event horizon is reduced by the Hawking th...
