    "abstract": "Classical communication through quantum channels may be enhanced by sharing\nentanglement. Superdense coding allows the encoding, and transmission, of up to\ntwo classical bits of information in a single qubit. In this paper, the maximum\nclassical channel capacity for states that are not maximally entangled is\nderived. Particular schemes are then shown to attain this capacity, firstly for\npairs of qubits, and secondly for pairs of qutrits.",
