ABSTRACT
The time evolution of multi-neutrino entanglement and correlations are studied in two-flavor collective neutrino oscillations, relevant for dense neutrino environments, building upon previous works. Specifically, simulations performed of systems with up to 12 neutrinos using Quantinuum’s H1-1 20 qubit trapped-ion quantum computer are used to compute -tangles, and two- and three-body correlations, probing beyond mean-field descriptions. -tangle rescalings are found to converge for large system sizes, signaling the presence of genuine multi-neutrino entanglement.
