Instead of a pure state, we consider the signal-ancilla pair in a mixed state, purified by a \"witness\". Thus, the signal-witness correlation limits the resource available from the signal-ancilla correlation. Our formula characterizes the utility of different forms of resources, including noisy or limited entanglement assistance, for classical communication.
