We investigate whether for any entangled state, including bound entangled states, there exists a quantum channel the classical capacity of which can be increased by providing the state as an additional resource. We show, for any entangled state, the existence of a quantum memory channel the feedback-assisted classical capacity with product encodings of which can be increased by using the state as a resource. Using a different channel construction, we also provide a sufficient entropic condition for an advantage in classical communication and thus provide an example of a state that is not distillable by means of one-way LOCC, but can provide an advantage in the classical communication. As separable states cannot provide such an advantage, our condition also provides an entanglement witness. |
