The relative population transport (net change in state populations) Δ P t for the diabatic CZ gate, including the first two leakage levels. The rotation in |20⟩ ↔ |11⟩ has been calibrated to 2π. Highlighted are the off-diagonal elements due to the couplings between higher levels, with average relative population transport |Δ P t| shown below.
