The embeddings associated with the (a) 1D and (b) 2D inverse problems are shown. The 1D embedding is obtained by removing vertices and edges from the physical hardware graph in Fig. 2a. The 2D embedding is obtained by contracting edges (in particular, the red edges) and removing edges from the Chimera graph in Fig. 2b.
