The experiment is described at p26 of http://arxiv.org/abs/quant-ph/0402001
In this experiment we see that we sum measurement results and not measure the sum.
Is then the quantum measurement operator not :
$$S=A\otimes B\otimes\mathbb{1_{64}}-\mathbb{1_{4}}\otimes A\otimes B'\otimes\mathbb{1_{16}}+\mathbb{1_{16}}\otimes A'\otimes B\otimes\mathbb{1_{4}}+\mathbb{1_{64}}\otimes A'\otimes B'$$
Since we have the eigenvalues of S $$eig(S)\in\{-4,-2,0,2,4\}$$ ?
