The QUBO problem is to minimize or maximize a quadratic form $y=x^T Q x$, where $x$ is a Boolean vector and $Q$ is a real square matrix.
Ref. 1 gives a new transformation from 3-SAT to QUBO:
For a given graph $G=(V,E)$, we can define a classical spin model:
$$ H=\sum{(i, j) \in E} J{i j} \sigma_i \sigmaj+\sum{i \in V} h_i \sigma_i $$
I didn't find good references for this reduction, but it seems that this reduction is trivial:
