Here we use the set of measurement {α, β, γ} as an example. The clicks of eight detectors correspond to the eight outcomes of each set of measurements, respectively, such as D1 → {1, 1, 1}, D2 → {1, 1, −1}, D3 → {1, −1, 1}, D4 → {1, −1, −1}, D5 → {−1, 1, 1}, D6 → {−1, 1, −1}, D7 → {−1, −1, 1}, D8 → {−1, −1, −1}.
