Abstract:The teleportation of an unknown quantum state from one observer to another is of great importance in quantum information. In the standard teleportation scheme, a maximally entangled state is demanded. However, it is difficult to prepare such states in practice, and real entangled states are always partly entangled. We present a scheme to teleport an unknown quantum state using two partly entangled states. We show that the teleportation can be realized with a certain probability.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
