Linear quantum trajectories: Applications to continuous projection measurements
arXiv:quant-ph/9801042 · doi:10.1103/PhysRevA.57.2301
Abstract
We present a method for obtaining evolution operators for linear quantum trajectories. We apply this to a number of physical examples of varying mathematical complexity, in which the quantum trajectories describe the continuous projection measurement of physical observables. Using this method we calculate the average conditional uncertainty for the measured observables, being a central quantity of interest in these measurement processes.
