Description
Quantum algorithms based on the variational quantum eigensolver (VQE) and ADAPT-VQE are implemented for ab initio nuclear structure calculations within the no-core shell model and full configuration interaction shell model frameworks, enabling an efficient treatment of nuclear many-body systems in large configuration spaces. Building on this, the Generator Coordinate Method (GCM) is formulated on quantum platforms through Quantum GCM (QuGCM) and ADAPT-GCIM, establishing a connection between collective nuclear behavior and underlying many-body dynamics. The results indicate that integrating GCM with quantum algorithms can provide an effective framework for handling superpositions of configurations and large-amplitude collective motion. This approach incorporates key features such as collective coordinates and quantum tunneling, and is expected to be fruitful for future studies of collective excitations and fission-related phenomena within nuclear structure theory.
