    "abstract": "We examine the dynamics of a qubit stored in the motional degrees of freedom\nof an ultra-cold ion in an ion trap which is subject to the decoherence effects\nof a finite-temperature bath. We discover an encoding of the qubit, in two of\nthe motional modes of the ion, which is stable against the occurrence of either\nnone or one quantum jump. For the case of a zero-temperature bath we describe\nhow to transfer only the information concerning the occurrence of quantum jumps\nand their types to a measuring apparatus, without affecting the ion\u0027s motional\nstate significantly. We then describe how to generate a unitary restoration of\nthe qubit given the jump information, through Raman processes generated by a\nseries of laser pulses.",
