    "abstract": "The stability and instability of quantum motion is studied in the context of\ncavity quantum electrodynamics (QED). It is shown that the Jaynes-Cummings\ndynamics can be unstable in the regime of chaotic walking of an atom in the\nquantized field of a standing wave in the absence of any other interaction with\nenvironment. This quantum instability manifests itself in strong variations of\nquantum purity and entropy and in exponential sensitivity of fidelity of\nquantum states to small variations in the atom-field detuning. It is quantified\nin terms of the respective classical maximal Lyapunov exponent that can be\nestimated in appropriate in-out experiments.",
