Multi-server blind quantum computation protocol with limited classical communication among servers

A user who does not have a quantum computer but wants to perform computations may delegate his computation cloud server. In order that the delegation works, it must be assured no evil server can obtain any important information on computation. The blind protocol was proposed as way for protect from unauthorized actions of Among protocols thus far, with two servers sharing entanglement, while require resource, allow communicate even after this paper, we propose protocol, by extend two-server multiple servers, which remains secure if some each other Dummy gates and circuit modeled brickwork states play crucial role in new protocol.
