    "abstract": "A single quantum system, such as a hydrogen atom, can transmit a Cartesian\ncoordinate frame (three axes). For this it has to be prepared in a\nsuperposition of states belonging to different irreducible representations of\nthe rotation group. The algorithm for decoding such a state is presented, and\nthe fidelity of transmission is evaluated.",
