    "abstract": "We suggest a physical interpretation of the Uhlmann amplitude of a density\noperator. Given this interpretation we propose an operational approach to\nobtain the Uhlmann condition for parallelity. This allows us to realize\nparallel transport along a sequence of density operators by an iterative\npreparation procedure. At the final step the resulting Uhlmann holonomy can be\ndetermined via interferometric measurements.",
