Abstract:
We present a quantum error correction code which protects three quantum bits (qubits) of quantum information against one erasure, i.e., a single-qubit arbitrary error at a known position. The present code has a high encoding efficiency since only one auxiliary qubit is needed for one message qubit on average. In addition, we note that the code can also work even in a worse case that the interaction with environment causes a leakage out of the qubit space. The code may have some applications in the storage of quantum information for a small-scale quantum computing, quantum information processing, and quantum communication.
