Abstract

It is shown that the number-phase Wigner function defines uniquely the respective density operator. Relations between the Glauber-Sudarshan distribution P(α) and the number-phase Wigner function is found. This result is then generalised to the case of the Cahil-Glauber distributions W^(s)(α), -1≤ s ≤ 1.
