Abstract: | Following the previous paper in which quantum teleportation is rigorously discussed with coherent entangled states given
by beam splittings, we further discuss two types of models, the perfect teleportation model and non-perfect teleportation
model, in a general scheme. Then the difference among several models, i.e., the perfect models and the non-perfect models,
is studied. Our teleportation models are constructed by means of coherent states in some Fock space with counting measures,
so that our model can be treated in the frame of usual optical communication.
