    "abstract": "We discuss a model of repeated measurements of position in a quantum system\nwhich is monitored for a finite amount of time with a finite instrumental\nerror. In this framework we recover the optimum monitoring of a harmonic\noscillator proposed in the case of an instantaneous collapse of the\nwavefunction into an infinite-accuracy measurement result. We also establish\nnumerically the existence of an optimal measurement strategy in the case of a\nnonlinear system. This optimal strategy is completely defined by the spectral\nproperties of the nonlinear system.",
