• Abstract summary: Simulations of Dirac neutrino-neutrino interactions performed on D-Wave Inc.'s tt Advantage 5000+ qubit quantum annealer. The D-Wave tt Advantage annealer is shown to be able to reproduce time evolution with the precision of a classical machine for small number of neutrinos. However, it suffers from poor scaling in qubit-count with the number of neutrinos.

• Abstract: In extreme environments such as core-collapse supernovae, neutron-star mergers, and the early Universe, neutrinos are dense enough that their self-interactions significantly affect, if not dominate, their flavor dynamics. In order to develop techniques for characterizing the resulting quantum entanglement, I present the results of simulations of Dirac neutrino-neutrino interactions that include all three physical neutrino flavors and were performed on D-Wave Inc.'s {\tt Advantage} 5000+ qubit quantum annealer. These results are checked against those from exact classical simulations, which are also used to compare the Dirac neutrino-neutrino interactions to neutrino-antineutrino and Majorana neutrino-neutrino interactions. The D-Wave {\tt Advantage} annealer is shown to be able to reproduce time evolution with the precision of a classical machine for small number of neutrinos and to do so without Trotter errors. However, it suffers from poor scaling in qubit-count with the number of neutrinos. Two approaches to improving the qubit-scaling are discussed, but only one of the two shows promise.

• Spectral splits and entanglement entropy in collective neutrino oscillations [0.0]
  We find an intriguing connection between the entropy of entanglement of individual neutrinos with the rest of the ensemble. For various types of neutrino spectra, we demonstrate that the entanglement entropy is highest for the neutrinos whose locations in the energy spectrum are closest to the spectral split(s) This trend demonstrates that the quantum entanglement is strongest among the neutrinos that are close to these splits, a behavior that seems to persist even as the size of the many-body system is increased.
