Benchmarking of Quantum Magic in 3-flavor Collective Neutrino Oscillations

ORAL

Abstract

In core-collapse supernovae and neutron star mergers, neutrinos are sufficiently dense that neutral-current interactions between neutrinos are a significant factor in neutrino flavor dynamics. These interactions and the entanglement they impart make the dynamics of the resulting collective neutrino oscillations (CNOs), which may influence astrophysical processes such as nucleosynthesis, challenging to compute on classical devices. Thus, quantum computing may be the most promising path towards simulating CNOs at scale. In addition to entanglement, a system must have high magic for quantum advantage to be possible in its simulation. We benchmark the evolution of magic of 3-flavor CNOs and find that if the initial state is purely compsed of νe, the final values of magic per neutrino decrease as the number of neutrinos decreases, while the same is not true for systems with neutrinos in all three flavors.
