摘要：

Teleportation of a d-dimensional quantum state via a pure but partially entangled channel is studied. Two schemes are presented for conclusive teleportation aiming at both obtaining a faithful replica with optimal probability and achieving a maximum average fidelity of teleportation when conclusive teleportation fails. A single pair entanglement concentration scheme is also constructed. (C) 2002 Elsevier Science B.V. All rights reserved.
