    "abstract": "The dynamical status of isolated quantum systems, partly due to the linearity\nof the Schrodinger equation is unclear: Conventional measures fail to detect\nchaos in such systems. However, when quantum systems are subjected to\nobservation -- as all experimental systems must be -- their dynamics is no\nlonger linear and, in the appropriate limit(s), the evolution of expectation\nvalues, conditioned on the observations, closely approaches the behavior of\nclassical trajectories. Here we show, by analyzing a specific example, that\nmicroscopic continuously observed quantum systems, even far from any classical\nlimit, can have a positive Lyapunov exponent, and thus be truly chaotic.",
