Hidden parameters in open-system evolution unveiled by geometric phase
arXiv:1005.2992 · doi:10.1103/PhysRevA.82.052107
Abstract
We find a class of open-system models in which individual quantum trajectories may depend on parameters that are undetermined by the full open-system evolution. This dependence is imprinted in the geometric phase associated with such trajectories and persists after averaging. Our findings indicate a potential source of ambiguity in the quantum trajectory approach to open quantum systems.
