    "abstract": "Building on Peres\u0027s idea of \"Delayed-choice for extanglement swapping\" we\nshow that even the degree to which quantum systems were entangled can be\ndefined after they have been registered and may even not exist any more. This\ndoes not arise as a paradox if the quantum state is viewed as just a\nrepresentative of information. Moreover such a view gives a natural\nquantification of the complementarity between the measure of information about\nthe input state for teleportation and the amount of entanglement of the\nresulting swapped entangled state.",
