    "abstract": "This paper presents a simple model for repeated measurement of a quantum\nsystem: the evolution of a free particle, simulated by discretising the\nparticle\u0027s position. This model is easily simulated by computer and provides a\nuseful arena to investigate the effects of measurement upon dynamics, in\nparticular the slowing of evolution due to measurement (the `quantum Zeno\neffect\u0027). The results of this simulation are discussed for two rather different\nsorts of measurement process, both of which are (simplified forms of)\nmeasurements used in previous simulations of position measurement. A number of\ninteresting results due to measurement are found, and the investigation casts\nsome light on previous disagreements about the presence or absence of the Zeno\neffect.",
