    "abstract": "We study the measurement process by treating classical detectors entirely\nquantum mechanically. As a generic model we use a point-contact detector\ncoupled to an electron in a quantum dot and tunneling into the continuum.\nTransition to the classical description and the mechanism of decoherence are\ninvestigated. We concentrate on the influence of the measurement on the\nelectron decay rate to the continuum. We demonstrate that the Zeno (or the\nanti-Zeno) effect requires a nonuniform density of states in the continuum. In\nthis case we show that the anti-Zeno effect relates only to the average decay\nrate, whereas for sufficiently small time the Zeno effect always takes place.\nWe discuss the experimental consequences of our results and the role of the\nprojection postulate in a measurement process.",
