We develop a new formalism to investigate the effects of gravity and curvature on quantum communication protocols, in particular focusing on quantum key distribution setups. We are able to show that the effects can play a role, in particular when the aim is to establish entanglement to be used as a resource for quantum information processing between two distant sources in the gravitational field. Our results indicate that the spacetime acts as a channel and we provide a systematic way to understand how such channel affects communication. We study the impact on current and future planned quantum commuincation networks.
