- Abstract: Fault-tolerant quantum computers promise to provide direct simulations for
neutrino oscillations in classically intractable scenarios. In today noisy
quantum hardware, encoding neutrino in a multi-qubit system requires redundant
basis and tricky entangling gates. We study a qutrit encoding for a
three-flavor neutrino with the PMNS matrix and time evolution expressed in
terms of single qutrit gates. The qutrit is tuned up from the multi-level
structure of a IBM superconducting transmon. High-fidelity gate control and
readout are engineered using Qiskit Pulse by programming microwave pulses. Our
simulation results align well with analytical calculations in three oscillation
cases: in vacuum, with CP-violation, and in interaction with matter.
