摘　　要：For the Noh,Fougères and Mandel(NFM)operational quantum phase description,which is based on an eightport homodyne-detection,we derive the minimum uncertainty states for the number-difference-phase uncertainty relation.The derivation makes full use of the newly constructed|q,τ)representation which is the common eigenvector of the two-mode photon number-difference a^(+)a-b^(+)b and(a+b^(+))(a^(+)+b).
