Site- and bond-percolation thresholds inKn,n-based lattices: Vulnerability of quantum annealers to random qubit and coupler failures on chimera topologies
Physical review. E
We estimate the critical thresholds of bond and site percolation on nonplanar, effectively two-dimensional graphs with chimera like topology. The building blocks of these graphs are complete and symmetric bipartite subgraphs of size 2n, referred to as K_n,n graphs. For the numerical simulations we use an efficient union-find based algorithm and employ a finite-size scaling analysis to obtain the critical properties for both bond and site percolation. We report the respective percolationdoi:10.1103/physreve.93.042128 pmid:27176275 fatcat:6ucl4xp22ng7lctkx7f5mdesry
