Zakopane 2026 Conference on Nuclear Physics

Nuclear many-body calculations on classical computers typically involve Monte Carlo simulations. These suffer from the fermionic sign problem where the signal-to-noise ratio diminishes as the system size grows. Moreover, these simulations are performed in Euclidean which complicates calculations of real-time dynamics from such simulations. Quantum computation avoids these issues by unitary evolution in real-time. In this talk, I present several algorithms to calculate elastic and inelastic reaction matrix elements on quantum computers. Results for two-particle phase shifts, E1 transition matrix elements and mass gap calculations are presented.
