    "abstract": "The evolution of a quantum system under observation becomes retarded or even\nimpeded. We review this ``quantum Zeno effect\u0027\u0027 in the light of the criticism\nthat has been raised upon a previous attempt to demonstrate it, of later\nreexaminations of both the projection postulate and the significance of the\nobservations, and of the results of a recent experiment on an individual cold\natom. Here, the micro-state of the quantum system gets unveiled with the\nobservation, and the effect of measurement is no longer mixed up with dephasing\nthe object\u0027s wave function by the reactive effect of the detection. A procedure\nis outlined that promises to provide, by observation, an upper limit for the\ndelay of even an exponential decay.",
