    "abstract": "Quantum teleportation of qudits is revisited. In particular, we analyze the\ncase where the quantum channel corresponds to a non-maximally entangled state\nand show that the success of the protocol is directly related to the problem of\ndistinguishing non-orthogonal quantum states. The teleportation channel can be\nseen as a coherent superposition of two channels, one of them being a maximally\nentangled state thus, leading to perfect teleportation and the other,\ncorresponding to a non-maximally entangled state living in a subspace of the\nd-dimensional Hilbert space. The second channel leads to a teleported state\nwith reduced fidelity. We calculate the average fidelity of the process and\nshow its optimality.",
