Pseudo-density operator tomographic reconstruction. Theoretical R123 PDO (a: since Im[R123] = 0, we only plot Re[R123]) compared with the real (b) and imaginary (c) part extracted by quantum state tomography. Below, theoretical models of the R12, R13 and R23 marginals (plots d, g and j, respectively) compared with the real (plots e, h and k) and imaginary (plots f, i and l) part of their tomographically reconstructed counterparts. Again, since in our model Im[R12] = Im[R13] = Im[R23] = 0, the corresponding theoretical plots have been omitted
