Scheme for Teleportation of a Multipartite Quantum State by Using a Single Entangled Pair as Quantum Channel
Xin-Wen Wang, Zhiyong Wang, Li-Xin Xia · Communications in Theoretical Physics · 2007
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.
