Conclusive teleportation of a<i>d</i>-dimensional unknown state

Abstract

We formulate a conclusive teleportation protocol for a system in d-dimensional Hilbert space utilizing the positive operator-valued measurement. The conclusive teleportation protocol ensures some perfect teleportation events when the channel is only partially entangled, at the expense of lowering the overall average fidelity. We discuss how much information remains in the inconclusive parts of the teleportation.
