Figure 2From: The deterministic pattern matching based on the parameterized quantum circuitThe universal circuit structure of HEA, which is composed of three qubits with three layers. For simplicity, the parameter θ of the operation \(R ( \theta )\) is omitted here and after. \(q_{2}\), \(q_{1}\) and \(q_{0}\) correspond to the qubits from top to downBack to article page
