Abstract: Quantum secure summation is the basis of quantum secure computation, which aims to compute the sum of participants ′ secrets on the premise of protecting the participants ′ private information. A three-party quantum secure summation protocol based on GHZ-like states is proposed, in which only quantum center has full quantum capabilities, and the other participants can only reflect or measure the received quantum states. Theoretical analysis shows that the proposed protocol can ensure correctness, that is, multi-party can finally successfully calculate the sum of their secrets. At the same time, the protocol can also resist participant attacks and external attacks, that is, neither external attackers nor internal participants can obtain any information except their own secrets and results. Finally, how to expand the participants of the agreement from three-party to multi-party is further discussed.

Key words: quantum communication, quantum secure multiparty computation, quantum secure summation; quantum center, GHZ-like states
