    "abstract": "A new scheme of quantum coding is presented. The scheme concerns the quantum\nstates to which Schumacher\u0027s compression does not apply. It is shown that two\nqubits can be encoded in a single qutrit in such a way that one can faithfully\nreconstruct the state of one qubit. Decision on which of these two qubits is to\nbe reconstructed can be made long after the encoding took place. The scheme\nsucceeds with the average probability of 2/3.",
