Illustration of the nesting scheme. In the left column, a C-degree nested graph is constructed by embedding a KN into a KC×N, with N=4 and C=1 (a and b) and C=4 (c and d). Red, thick couplings are energy penalties defined on the nested graph between the (i, c) nested copies of each logical qubit i. The right column shows the nested graphs after ME on the DW2 Chimera graph. Brown, thick couplings correspond to the ferromagnetic chains introduced in the process.
