The multimode even and odd coherent states (multimode Schroedinger cat states) are constructed for polymode parametric oscillators of the electromagnetic field. The evolution of the photon distribution function is evaluated explicitly. The distribution function is expressed in terms of the multivariable Hermite polynomials, its means and dispersions are calculated. The conditions for the existence of squeezing are formulated. The correlations among the different modes of Schroedinger cat states are studied.

Working from the Schroedinger's Cat paradigm, a series of experiments are constructed. The Bedford-Wang experiment is examined, and the ambiguity in its meaning is addressed. We eliminate this ambiguity by abandoning the idea of the triggering event, replacing the two-state system with a mirror that undergoes wave packet spreading. This creates an experimentally testable version of a modified Schroedinger's Cat experiment for which a null result is not the obvious outcome.
