Figure 4From: Ancilla-driven blind quantum computation for clients with different quantum capabilitiesSchematic structure of a circuit diagram which can be used to simulate the \(CNOT\) gate and arbitrary single-qubit gates. The operation \(HR_{Z}(\theta )\) in each rectangular box in this circuit diagram is simulated by the gadget in Fig. 2, and the CZ operation is implemented by the simulation in Fig. 3Back to article page
