摘要：
A new experimental scheme to teleport a unknown superposition of two coherent states with an equal amplitude but opposite phases between two parties under control of a number of controllers is proposed using only "yes/no" detectors, i.e., without photon counting. The protocol is conclusive in the sense that any party is able to recognize a failure or a possible success immediately after his measurement. The total success probability is derived which yields a maximal value of 1/2 independent of the number of controllers. (c) 2006 Elsevier B.V. All rights reserved.
