Abstract 

In the last decade, description of nuclei based only on nucleon-nucleon forces has been extended to increasingly large systems (A~100). These advances are due in part to the implementation of polynomially scaling many-body frameworks, in part to new systematically improvable nucleon-nucleon potentials rooted in the underlying strong force of quantum chromodynamics, and in part to increased power of computational facilities available. This impressive achievement notwithstanding, more exact solutions, and in general those of even larger systems, still pose a considerable challenge to first-principle calculations. Quantum computers have recently been used for the first time to solve real, physical problems. Although meager in complexity by current classical computational standards, more advanced quantum computers should be able extend the reach of quantum mechanical solutions to increasingly more complex problems. There is a need to find simple, but solvable problems in order to test the current limits of quantum architectures, and to provide useful feedback on how to improve the next and future generation of machines. Nuclear physics can augment the already rich testing ground for this. In this talk, I will present recent progress of nuclear calculations, focusing on nuclear coupled cluster theory, and how this can provide guidance on how to move forward with quantum computations. I will then emphasize recent calculations of the deuteron on two quantum architectures and provide information on how this is has paved the way for future work.
