Abstract: A molecular structure optimization system includes a quantum computer and a classical computer. The quantum computer uses a parameterized quantum circuit to calculate a loss function from a coordinate parameter of a target molecule. The classical computer updates the coordinate parameter and the circuit parameter based on the loss function, and determines optimum values of the circuit parameter and the coordinate parameter. The classical computer updates a provisional value of the circuit parameter while fixing the coordinate parameter and changing the circuit parameter. The classical computer updates a provisional value of the coordinate parameter while fixing the circuit parameter and changing the coordinate parameter.
