    "abstract": "This article describes the AC Stark, Stern-Gerlach, and Quantum Zeno effects\nas they are manifested during continuous interferometric measurement of a\ntwo-state quantum system (qubit). A simple yet realistic model of the\ninterferometric measurement process is presented, and solved to all orders of\nperturbation theory in the absence of thermal noise. The statistical properties\nof the interferometric Stern-Gerlach effect are described in terms of a\nFokker-Plank equation, and a closed-form expression for the Green\u0027s function of\nthis equation is obtained. Thermal noise is added in the form of a\nexternally-applied Langevin force, and the combined effects of thermal noise\nand measurement are considered. Optical Bloch equations are obtained which\ndescribe the AC Stark and Quantum Zeno effects. Spontaneous qubit transitions\nare shown to be observationally equivalent to transitions induced by external\nLangevin forces. The effects of delayed choice are discussed. Practical\nexperiments involving trapped ions are suggested. The results are relevant to\nthe design of qubit readout systems in quantum computing, and to single-spin\ndetection in magnetic resonance force microscopy.",
