Number of measurements for every element of the four-qubit basis. The experimental values for 〈σ_z〉 are (0.70, −0.26, −0.27, 0.41) while the ideal values are (0.71, −0.71, −0.71, 0.71). Notice that the mapping of reordering the qubits has been inverted to achieve the results in the |g₁p₁g₂p₂〉 basis.
