    Abstract

    By considering a quantum superposition of classical messages, the capacities for general nonlocalunitary operations were shown to satisfy the inequality c+ E≤Ev+Ev -. In order to show such inequalities, it was demonstrated that it was possible to put an upper limit on the dimension of the ancilla required for the communication process. This paper presents a promising way of proving equalities which was by developing an efficient scheme for remote state preparation of bidirectional ensembles.
