    "abstract": "Beyond their use as numerical tools, quantum trajectories can be ascribed a\ndegree of reality in terms of quantum measurement theory. In fact, they arise\nnaturally from considering continuous observation of a damped quantum system. A\nparticularly useful form of quantum trajectories is as linear (but non-unitary)\nstochastic Schrodinger equations. In the limit where a strong local oscillator\nis used in the detection, and where the system is not driven, these quantum\ntrajectories can be solved. This gives an alternate derivation of the\nprobability distributions for completed homodyne and heterodyne detection\nschemes. It also allows the previously intractable problem of real-time\nadaptive measurements to be treated. The results for an analytically soluble\nexample of adaptive phase measurements are presented, and future developments\ndiscussed.",
