    "abstract": "We propose two quantum error correction schemes which increase the maximum\nstorage time for qubits in a system of cold trapped ions, using a minimal\nnumber of ancillary qubits. Both schemes consider only the errors introduced by\nthe decoherence due to spontaneous emission from the upper levels of the ions.\nContinuous monitoring of the ion fluorescence is used in conjunction with\nselective coherent feedback to eliminate these errors immediately following\nspontaneous emission events, and the conditional time evolution between quantum\njumps is removed by symmetrizing the quantum codewords.",
