In this work, we present a quantum simulation approach to model the collective behavior of three-flavor neutrinos using qutrit-based quantum circuits. Each neutrino is represented by a qutrit—a quantum system with three energy levels—allowing a natural encoding of the SU(3) flavor structure. We use the Trotter–Suzuki decomposition to approximate the time evolution generated by the collective Hamiltonian. We then design quantum circuits composed of qutrit gates corresponding to these decomposed unitary operators. The simulation results show that the qutrit framework can effectively reproduce key features of three-flavor oscillations.
