Surface-code decoding as a random-bond Ising model
= Surface-code decoding as a random-bond Ising model
{c}
For independent bit flips, summing the <probabilities> of all error chains in one syndrome and logical class equals, up to a class-independent factor, the partition function of a random-bond <Ising model>. A reference error fixes bond signs and products of star stabilizers become <Ising spin> configurations.
