  Entanglement generation in microcavity exciton-polaritons is an interesting
application of the peculiar properties of these half-light/half-matter
quasiparticles. In this paper we theoretically investigate their luminescence
dynamics and entanglement formation in single, double, and triple cavities. We
derive general expressions and selection rules for polariton-polariton
scattering. We evaluate a number of possible parametric scattering schemes in
terms of entanglement, and identify the ones that are experimentally most
promising.
