摘要：

The phase properties of fields generated from the vacuum in the m-photon down-conversion process with quantum pumping are studied from the point of view of the Hermitian phase formalism. The joint phase distribution P(theta(a),theta(b)) as well as the marginal phase distribution P(theta(a)) for the signal mode are derived and illustrated graphically for m = 2, 3, and 4. The relationship between these phase distributions and the "classical" distributions obtained by integrating the Q function is established. It is shown that the classical phase distribution is a result of an averaging procedure that leads to a broadening of the phase distribution.
