Line Plot from Scientific Research

Final single-particle fidelities {F}_{{{rm{sp}}}}= root N of {F} starting from initial ground states with transverse-field value g x . The target state is the z -polarized product state. The grey dashed line denotes the fidelity threshold ( {F}_{{{rm{sp}}}}^* = 0.99 , F * 0.72): it is surpassed for most initial states except at the critical point g x 1 (cyan dot). The red vertical dashed lines contain the training region.
