Abstract
A classical computer outputs a Hamiltonian and initial information of a parameter expressing a quantum circuit. The classical computer, according to a parameter expressing a first quantum circuit that was output from a quantum computer and was generated by quantum computation employing a Variational Quantum Eigensolver (VQE) based on the Hamiltonian and the initial information, generates a parameter expressing a second quantum circuit including a rotation gate and outputs the parameter expressing the second quantum circuit. The classical computer, based on measurement results of quantum computation that were output from the quantum computer and computed according to the parameter expressing the second quantum circuit, based on the Hamiltonian, and based on a derivative function of the Hamiltonian, generates a derivative function of energy corresponding to the Hamiltonian and outputs the derivative function of energy.
