    "abstract": "The normalized state $\\ket{\\psi(t)}=c_1(t)\\ket{1}+c_2(t)\\ket{2}$ of a single\ntwo-level system performs oscillations under the influence of a resonant\ndriving field. It is assumed that only one realization of this process is\navailable. We show that it is possible to approximately visualize in real time\nthe evolution of the system as far as it is given by $|c_2(t)|^2$. For this\npurpose we use a sequence of particular unsharp measurements separated in time.\nThey are specified within the theory of generalized measurements in which\nobservables are represented by positive operator valued measures (POVM). A\nrealization of the unsharp measurements may be obtained by coupling the\ntwo-level system to a meter and performing the usual projection measurements on\nthe meter only.",
