Abstract Blind quantum computation enables a client with limited quantum capabilities to delegate a powerful quantum computer for performing confidential quantum computation. This paper identifies a security loophole in the initial universal half-blind quantum computation protocol and resolves it using operation teleportation. Simultaneously, to minimize quantum resource consumption for both the client and the server, the proposed protocol relies on the universal gate set H, T, and CX, and only necessitates the client’s ability to prepare qubits in the eigenstates of Pauli gates X and Y or measure qubits based on these gates. Finally, a sample example is provided to illustrate the proposed protocol effectively.
