Quantum Computing for Neutrino-nucleus Scattering

Understand

Neutrino-nucleus cross section uncertainties are expected to be a dominant systematic in future accelerator neutrino experiments.

• The cross sections are determined by the linear response of the nucleus to the weak interactions of the neutrino, and are dominated by energy and distance scales of the order of the separation between nucleons in the nucleus.
• These response functions are potentially an important early physics application of quantum computers.
• Here we present an analysis of the resources required and their expected scaling for scattering cross section calculations.
