    "abstract": "We show that standard teleportation with an arbitrary mixed state resource is\nequivalent to a generalized depolarizing channel with probabilities given by\nthe maximally entangled components of the resource. This enables the usage of\nany quantum channel as a generalized depolarizing channel without additional\ntwirling operations. It also provides a nontrivial upper bound on the\nentanglement of a class of mixed states. Our result allows a consistent and\nstatistically motivated quantification of teleportation success in terms of the\nrelative entropy and this quantification can be related to a classical\ncapacity.",
