    "abstract": "The evolution of a quantum system is supposed to be impeded by measurement of\nan involved observable. This effect has been proven indistinguishable from the\neffect of dephasing the system\u0027s wave function, except in an individual quantum\nsystem. The coherent dynamics, on an optical E2 line, of a single trapped ion\ndriven by light of negligible phase drift has been alternated with\ninterrogations of the internal ion state. Retardation of the ion\u0027s nutation,\nequivalent to the quantum Zeno effect, is demonstrated in the statistics of\nsequences of probe-light scattering \u0027\u0027on\u0027\u0027 and \u0027\u0027off\u0027\u0027 detections, the latter\nrepresenting back-action-free measurement.",
