Abstract

Erratum to Phys. Rev. X 4, 021008 (2014): The critical exponent associated with the ferromagnetic susceptibility was computed incorrectly. Furthermore, Ising ferromagnets on the Chimera topology have the same universality class as two-dimensional Ising ferromagnets.

Highlights

In Ref. [1], Katzgraber et al studied Ising spins on the Chimera topology [2] of the D-Wave Two quantum annealing machine both in the spin-glass (SG) as well as the ferromagnetic (FM) sector
