Blind quantum computation refers to the delegation of complex computation from a client with limited quantum capabilities or complete classical abilities to a server possessing ample quantum power.This reduces computational demands from the client.To reduce the economic pressure of the client and improve the execution effectiveness of blind quantum computation protocols,this paper introduces two enhanced measurement-based universal blind quantum computation protocols utilizing single-particle measurements.These protocols cater to quantum inputs featuring either real or complex coefficients.Each protocol involves two participants:the client,responsible for quantum state measurements and the exchange of classical or quantum information,and the server,tasked with preparing quantum states without measurement requirements.These protocols stand in contrast to the existing blind quantum computation approaches wherein the client solely undertakes measurements.The proposed protocols considerably reduce both the client's quantum and delegated costs while maintaining correctness,universality,and the concept of blindness.
