D-wave binary quadratic model
WebApr 30, 2024 · The Ising model is traditionally used in statistical mechanics. Variables are “spin up” ( ↑) and “spin down” ( ↓ ), states that correspond to +1 and −1 values. Relationships between the spins, represented by couplings, are correlations or anti-correlations. The objective function expressed as an Ising model is as follows: where ...
