Over the recent years, there has been a growing interest in using Noisy Intermediate-Scale Quantum (NISQ) computers to simulate physical dynamics. In previous studies, neutrino oscillation has been demonstrated on two-level quantum processors using qubits to encode information and perform calculations. In this work, we implement a more direct quantum simulation of the evolution of a three-flavor neutrino by harnessing the power of three-dimensional quantum systems. We employ the anharmonicity of an IBM superconducting quantum computer to access its third energy level to realize a transmon qutrit. Using Qiskit Pulse and Q-CTRL to calibrate pertinent pulses to represent SU(3) quantum gates, we simulate neutrino oscillation by means of the time evolution of the qutrit.
