We investigate the consequences of space-time being curved on space-based quantum communication protocols. We analyze tasks that require either the exchange of single photons in a certain entanglement distribution protocol or beams of light in a continuous-variable quantum key distribution scheme. We find that gravity affects the propagation of photons, therefore adding additional noise to the channel for the transmission of information. The effects could be measured with current technology.

  1. Gravitational redshift as a quantum channel: modeling the effects of gravitational redshift in quantum optics

    quant-ph 2026-08 conditional novelty 7.0 of 10

    Gravitational redshift cannot be represented by any finite set of smooth frequency modes, and the corrected finite-mode description is a Gaussian quantum channel built from a unitary dilation of the non-unitary compression.
