Nuclear Physics Seminar in Tate 301-20
Speaker: Alessandro Roggero, University of Washington
Subject: Quantum Computing for Nuclear Physics

Quantum Computers have the potential to dramatically extend the reach of our theoretical modelling of complex quantum many body systems. In this talk I will explore the impact that this technology can have on the study of structure and reactions of atomic nuclei. As an example, an ab-initio description of nuclear dynamics is currently out of reach for most systems of interest, however with only a mid-sized quantum computer efficient calculations of both inclusive and exclusive nuclear cross sections would be possible. In particular I will present an application of this strategy to describe reactions of relevance for long base-line neutrino experiments.
Current generations quantum devices are however too small and too noisy to already tackle realistic problems in nuclear physics, in the last part of the talk I will discuss some of the challenges one has to face when implementing practical quantum algorithms on today's quantum processors using a simple toy model for the triton as example.
