Secure multiparty computing is an important class of cryptographic primitives and is widely used in electronic voting, data mining, blockchain, cloud computing and other fields. In this paper, we propose an efficient secure multiparty quantum computation protocol based on quantum entanglement and the Euler theorem. In this protocol, all participants can safely compute multivariate polynomial functions with the help of a semitrusted third party. A performance analysis shows that the protocol is correct and can resist some common external and internal attacks. Additionally, the proposed protocol not only improves particle detection efficiency but also effectively reduces the communication complexity.
