    "abstract": "We study the quantum Zeno effect and the anti-Zeno effect in the case of\n`indirect\u0027 measurements, where a measuring apparatus does not act directly on\nan unstable system, for a realistic model with finite errors in the\nmeasurement. A general and simple formula for the decay rate of the unstable\nsystem under measurement is derived. In the case of a Lorentzian form factor,\nwe calculate the full time evolutions of the decay rate, the response of the\nmeasuring apparatus, and the probability of errors in the measurement. It is\nshown that not only the response time but also the detection efficiency plays a\ncrucial role. We present the prescription for observing the quantum Zeno and\nanti-Zeno effects, as well as the prescriptions for avoiding or calibrating\nthese effects in general experiments.",
