Nuclear two point correlation functions on a quantum computer

The calculation of dynamic response functions is expected to be an early application benefiting from rapidly developing quantum hardware resources. ability calculate real-time quantities strongly correlated systems one the most exciting applications that can easily reach beyond capabilities traditional classical hardware. Response fermionic at moderate momenta and energies corresponding roughly Fermi energy system are a potential because relevant operators nearly local, resolved in moderately short real time, reducing spatial resolution gate depth required. This particularly case quasielastic electron neutrino scattering nuclei, topic great interest nuclear particle physics communities directly related experiments designed probe properties. In this work we use current error mitigation protocols for highly simplified model through calculations 2-point time correlation function modified Fermi-Hubbard two dimensions with three distinguishable nucleons on four lattice sites.
