Title: Quantum simulations of collective neutrino oscillations

 

Abstract:

 

During a core-collapse supernova explosion, most of the energy released is carried away by the emitting neutrinos. To understand the dynamics of this explosion, we have to treat the neutrino transport in completion. However, the extreme conditions inside the supernova core allow neutrinos not only to frequently interact with matter but also with each other, which makes it a highly non-linear many-body problem with 10^58 neutrinos. Even with state-of-the-art computational methods such as tensor networks, this problem cannot be solved on classical computers. In fact, these simulations become even more complicated when a more realistic scenario with three active flavors is considered. Quantum simulations are a more natural way to simulate such quantum many-body systems. Simulations for collective neutrino oscillations on quantum computers have already been attempted but only few-neutrino systems could be simulated in such full-fledged quantum computations because of quantum hardware limitations. However, in the current noisy intermediate-scale quantum era, it is more efficient to employ a hybrid quantum-mechanical algorithm to solve this problem. In this talk, I will discuss my attempts to employ the hybrid quantum-classical algorithm to simulate collective neutrino oscillation dynamics and present some recent results on the measure of quantum entanglement. We have also made the first attempts to incorporate all three flavors in the neutrino many-body problem and found several interesting features about the generation of quantum entanglement in such a system. I will also talk about this more realistic three-flavor scenario and the potential utilization of qutrit-based quantum computers to simulate this case.
