  1. Number of measurements for every element of the four-qubit basis. The experimental values for 〈σz〉 are (−0.37, −0.26, −0.34, −0.34) while the ideal values are (−0.5, −0.35, −0.5, −0.46). Notice that the mapping of reordering the qubits has been inverted to achieve the results in the |g1p1g2p2〉 basis.
