Query: How to encode the states of two non-entangled qubits in one qutrit?   A new scheme of quantum coding is presented. The scheme concerns the quantum
states to which Schumacher's compression does not apply. It is shown that two
qubits can be encoded in a single qutrit in such a way that one can faithfully
reconstruct the state of one qubit. Decision on which of these two qubits is to
be reconstructed can be made long after the encoding took place. The scheme
succeeds with the average probability of 2/3.
