Specifically, we present a method to lower bound this communication cost even when the amount of entanglement does not increase. Moreover, the bound applies even if the initial state is supplemented with unlimited entanglement in the form of EPR pairs, and the communication is allowed to be quantum mechanical.\n  We then apply the method to the determination of the communication cost of asymptotic entanglement concentration and dilution.
