Abstract: Abstract We propose two quantum error correction schemes which increase the maximum storage time for qubits in a system of cold trapped ions. Both schemes consider only the errors introduced by the decoherence due to spontaneous emission from the upper levels of the ions. A “watchdog” approach is adopted in conjunction with selective coherent feedback to eliminate these errors immediately following spontaneous emission events.
