This study explores multi-neutrino entanglement in collective neutrino oscillations using quantum computing. Results show genuine multi-neutrino entanglement emerges in dense environments, crucial for understanding neutrino behavior.
Area of Science:
- Quantum Information Science
- Nuclear Physics
- Astrophysics
Background:
- Collective neutrino oscillations are critical in dense astrophysical environments like supernovae.
- Understanding multi-neutrino entanglement is key to refining models beyond mean-field approximations.
Purpose of the Study:
- To investigate the time evolution of multi-neutrino entanglement and correlations.
- To explore entanglement dynamics in two-flavor collective neutrino oscillations.
- To probe beyond mean-field descriptions in dense neutrino systems.
Main Methods:
- Simulations of systems with up to 12 neutrinos were performed.
- Quantinuum's H1-1 20 qubit trapped-ion quantum computer was utilized.
- Computation of n-tangles and two- and three-body correlations.
Main Results:
- n-tangle rescalings were found to converge for large system sizes.
- Evidence for genuine multi-neutrino entanglement was identified.
- Two- and three-body correlations were computed to probe beyond mean-field behavior.
Conclusions:
- Genuine multi-neutrino entanglement is present in collective neutrino oscillations.
- Quantum computing provides a powerful tool for studying complex quantum phenomena in many-body systems.
- The findings advance our understanding of neutrino interactions in extreme environments.
