    "abstract": "We study the entanglement between the 2D vibrational motion and two ground\nstate hyperfine levels of a trapped ion, Under particular conditions this\nentanglement depends on the parity of the total initial vibrational quanta. We\nstudy the robustness of this quantum coherence effect with respect to the\npresence of non-dissipative sources of decoherence, and of an imperfect initial\nstate preparation.",
