Abstract: | In this paper, two schemes for teleporting an unknown
four-particle entangled W state is proposed. In the first scheme, two
partial entangled four-particle states are used as quantum channels, while
in the second scheme, four non-maximally entangled particle pairs are
considered as quantum channels. It is shown that the teleportation can be
successfully realized with certain probability, for both schemes, if a
receiver adopts some appropriate unitary transformations. It is also shown
that the successful probabilities of these two schemes are different. |
