Blind quantum computation (BQC) allows a client with limited quantum power todelegate his quantum computational task to a powerful server and still keep hisinput, output, and algorithm private. There are mainly two kinds of modelsabout BQC, namely circuit-based and measurement-based models. In addition, ahybrid model called ancilla-driven universal blind quantum computing (ADBQC)was proposed by combining the properties of both circuit-based andmeasurement-based models, where all unitary operations on the register qubitscan be realized with the aid of single ancillae coupled to the register qubits.However, in the ADBQC model, the quantum capability of the client is strictlylimited to preparing single qubits. If a client can only perform single-qubitmeasurements or a few simple quantum gates, he may also want to delegate hiscomputation to a remote server via ADBQC. This paper solves the problem andextends the existing model by proposing two types of ADBQC protocols forclients with different quantum capabilities, such as performing single-qubitmeasurements or single-qubit gates. Furthermore, in the proposed two ADBQCprotocols, clients can detect whether servers are honest or not with a highprobability by using corresponding verifiable techniques.
