文摘We present a theoretical scheme for perfect teleportation of an unknown multipartite two-level state by a single EPR （Einstein-Podolsky-Rosen） pair, and then generalize it to multilevel, i.e., an N-quNit state can be teleported by a single quNit entangled pair, with additional local unitary operations. The feature of the scheme is that teleporting a multipartite state with a reduced amount of entanglement costs less classical bits.
