In the Variational Quantum Eigensolver (VQE) algorithm, the sequential minimal optimization approach is known to be effective in reducing the number of energy evaluations [Nakanishi et al., Phys. Rev. Res., 2, 043158]. Since focusing on a small number of parameters simplifies the energy landscape, this approach can update the parameters to a local optimal solution after a few evaluations. However, it is practically difficult to handle a large number of parameters in a single step because the number of required evaluations grows exponentially. In this study, we estimate the number of evaluations required to update a set of commutative rotation gates simultaneously. In addition, we demonstrate that our method is applicable to a wide range of quantum gates and works efficiently in cases where fsim gates and multiplexed rotation gates are involved. These results provide valuable insights for designing quantum circuits suitable for sequential minimal optimization. |
