Glassy Chimeras Could Be Blind to Quantum Speedup:
... Note that spin glasses on two-dimensional square lattices have ν ≈ 3.45 [30]; i.e., spin glasses on the Chimera topology are close to two space dimensions. Interestingly, the phase transition to a spin-glass phase only occurs at zero temperature, despite the Chimera graph being nonplanar. Furthermor ...

This is different from (±1 ± 1)/ 2, which is what we would obtain if we applied the additivity postulate to the right-hand side of Eq. 10.5. T ...
