Subfigure a shows two-dimensional embeddings of state representation vectors produced by GQNQ on Ising model (ferromagnetic and antiferromagnetic) ground states, XXZ model (ferromagnetic and XY phase) ground states, locally rotated GHZ and W states. Subfigure b shows two-dimensional embeddings of the state representation vectors of squeezed thermal states, cat states and GKP states. In both subfigures, shaded areas are added to help visualize the various type of states. Note that the representation vectors generated by GQNQ of states of the same type are near to each other in the two-dimensional embeddings.
