    "abstract": "The driven non-linear duffing osillator is a very good, and standard, example\nof a quantum mechanical system from which classical-like orbits can be\nrecovered from unravellings of the master equation. In order to generated such\ntrajectories in the phase space of this oscillator in this paper we use a the\nquantum jumps unravelling together with a suitable application of the\ncorrespondence principle. We analyse the measured readout by considering the\npower spectra of photon counts produced by the quantum jumps. Here we show that\nlocalisation of the wave packet from the measurement of the oscillator by the\nphoton detector produces a concomitant structure in the power spectra of the\nmeasured output. Furthermore, we demonstrate that this spectral analysis can be\nused to distinguish between different modes of the underlying dynamics of the\noscillator.",
