    • For n43 = n65 = 0 the quantities cosM and sinM are not defined. However, when we calculate their expectation values in the continuous limit, this singularity is not essential as apparent from Eq. ( refmcoscon1).

    • This transformation is a rotation and reflection of phase space. The reflection results from the fact that the quarter half plate sits at this specific position before BSsub 5 . If it would sit in the upper arm before BSsub 5 the transformation would read tildex+ i tildep = (x+ip)eiθ2 , with no reflection. Note that in this case the difference n6-n5 does not define sinM(θ2-θ1) , but sinM(θ1-θ2) . This can be seen by taking the difference of the classical intensities I6- I5 at the detector pair D6/D5 .

    • Since coherent states are not orthogonal the higher moments of widehatcosφ, Eq. ( refcosop), do not agree with the higher moments of the NFM operators, Eq. (3).

    • Starting from the idea that the NFM scheme measures the quadratures of an arbitrary split input state | ψ >, U. Leonhardt and H. Paul (unpublished) have found the Q function of | ψ >.
