    "abstract": "We present a quantum error correction code which protects three quantum bits\n(qubits) of quantum information against one erasure, i.e., a single-qubit\narbitrary error at a known position. To accomplish this, we encode the original\nstate by distributing quantum information over six qubits which is the minimal\nnumber for the present task (see reference [1]). The encoding and error\nrecovery operations for such a code are presented. It is noted that the present\ncode is also a three-qubit quantum hidded information code over each qubit. In\naddition, an encoding scheme for hiding $n$-qubit quantum information over each\nqubit is proposed.",
