    "abstract": "We study general teleportation scheme with an arbitrary state of the pair of\nparticles (2 and 3) shared by Alice and Bob, and arbitrary measurements on the\ninput particle 1 and one of the members (2) of the pair on Alice\u0027s side. We\nfind an efficient iterative algorithm for identifying optimum local operations\non Bob\u0027s side. In particular we find that simple unitary transformations on his\nside are not always optimal even if particles 2 and 3 are perfectly entangled.\nWe describe the most interesting protocols in the language of extremal\ncompletely-positive maps.",
