Abstract
A quantitative lower bound on the communication of cost of general entanglement transformations is demonstrated. It is good enough to prove that the Lo-Popescu protocol of entanglement dilution is within a constant factor of being optimal. Furthermore, it can be used to show that there exist states whose communication cost for creation from ERP pairs is of the same order as their entanglement.
