Abstract
En 中文
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.
