Quantum resource redistribution drives spectral splits in dense neutrino gases
Michael Hite, Pooja Siwach
Whether a quantum many-body system can be efficiently simulated hinges not only on its size but also on how quantum resources are organized within it. We characterize the quantum r…
Three-flavor supernova neutrino simulation using a hybrid quantum-classical algorithm with qutrits
