摘要：

A reformulation of the well-known maximum-entropy principle in the interaction picture is shown. The advantage of this approach for the case in which the relevant operators in the interaction picture do not depend explicitly on time is stated. As an example, we study the dynamical evolution of the dispersions of the so-called slowly varying quadrature operators for the degenerate parametric amplifier and the temporal behavior of the squeezed states associated with this system.
