We describe a set of codes developed under the auspices of the Terascale Supernova Initiative to simulate the coherent, nonlinear evolution of the neutrino and antineutrino fields in the core collapse supernova environment. Ours are the first simulations to include quantum entanglement of neutrino flavor evolution on different neutrino trajectories. We find that neutrinos and antineutrinos can undergo coherent, collective transformations of their flavors which could affect supernova dynamics and nucleosynthesis. © 2006 IOP Publishing Ltd.
