Variational Quantum Eigensolver (VQE) calculations for estimating the ground state of quantum many-body systems are known as promising algorithms for current quantum computers. We will discuss orbital-optimized VQE calculations in nuclear structure calculations.We demonstrate the usefulness of the pair Unitary Coupled Cluster Doubles (pUCCD) ansatz in shell model calculations. Furthermore, we propose a VQE calculation method that combines the pUCCD ansatz with orbital optimization.
