Figure 4

Spatial non-adiabatic superposition scheme \(\pmb{\vert 1 \rangle \to\frac{1}{\sqrt{3}} ( \vert 1 \rangle - i \vert 2 \rangle - \vert 3 \rangle)}\) in the 3L approximation. \(T/\tau =400\). Sub-figures are the same as in Figure 2 and the fidelity shown in (b) is defined as \(F=\vert \langle \Psi _{\mathrm{target}}|\Psi (t)\rangle \vert ^{2}\).
