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.
