Abstract
Using the IWOP technique (integration within an ordered product), the authors find canonical coherent-state representations of two kinds of squeeze operators. These representations manifestly show that they are quantum maps imaged by certain symplectic transformations in coordinate-momentum phase space. In terms of this formalism the coherent-state propagator of parametric amplifiers is easily obtained.Keywords
