Liz, Apparently you don't understand QM very well. A decoherence PRODUCES an entanglement. All particle interactions result in entanglements of the interacting particles on the relations between their particle properties imposed by the conservation laws that govern particle interactions. Decoherences are particle interactions, therefore decoherences produce entanglements.
In general all particles are entangled with all other particles they have interacted with in their interaction histories....
