Various quantum computing methods for the calculation of the ground and the excited states of physical and chemical systems have been developed such as the full quantum eigensolver (FQE) method proposed in Shijie Wei et al. (2020). Compared to existing classical-quantum hybrid methods such as variational quantum eigensolver (VQE), the FQE method removes the classical optimizer and performs all the calculations on a quantum computer with faster convergence. In this study, we demonstrate the practical application of the FQE method to calculate the ground state energy for the Ising model and molecular hydrogen.
