    "abstract": "The formalism of Deutsch and Hayden is a useful tool for describing quantum\nmechanics explicitly as local and unitary, and therefore quantum information\ntheory as concerning a \"flow\" of information between systems. In this paper we\nshow that these physical descriptions of flow are unique, and develop the\napproach further to include the measurement interaction and mixed states. We\nthen give an analysis of entanglement swapping in this approach, showing that\nit does not in fact contain non-local effects or some form of superluminal\nsignalling.",
