    "abstract": "Each Bell state has the property that by performing just local operations on\none qubit, the complete Bell basis can be generated. That is, states generated\nby local operations are totally distinguishable. This remarkable property is\ndue to maximal quantum entanglement between the two particles. We present a set\nof local unitary transformations that generate out of partially entangled\ntwo-qubit state a set of four maximally distinguishable states that are\nmutually equally distant. We discuss quantum dense coding based on these\nalphabet states.",
