We prove that it is possible to remotely prepare an ensemble of noncommuting mixed states usingcommunication equal to the Holevo information for this ensemble. This remote preparation scheme maybe used to convert between different ensembles of mixed states in an asymptotically lossless way,analogous to concentration and dilution for entanglement.
