ABSTRACT Quantum communication is gradually shifting from terrestrial fiber‐optic communication to satellite‐based space communication. The impact of gravitational fields on quantum states in quantum communication protocols cannot be overlooked. In this paper, a general method to investigate how non‐inertial motion affects multiparty quantum communication is proposed. Specifically, we examine the influence of non‐inertial motion on the performance of the protocol based on measurement‐device‐independent multiparty quantum communication using continuous‐variable Greenberger–Horne–Zeilinger (CV GHZ) states. Our results demonstrate that the choice of system configuration and cryptographic scheme largely determines the effects of gravitational fields.
