Anonymous multi-party quantum computation with a third party

Abstract

We reconsider and modify the second secure multi-party quantum addition protocol proposed in our original work. We show that the protocol is an anonymous multi-party quantum addition protocol rather than a secure multi-party quantum addition protocol. Through small changes, we develop the protocol to propose, for the first time, anonymous multiparty quantum computation with a third party, who faithfully executes protocol processes, but is interested in the identity of the data owners. Further, we propose a new anonymous multiparty quantum protocol based on our original protocol. We calculate the success probability of the proposed protocols, which is also a modification of the success probability of the original protocols.
