Quantum teleportation of entanglement via quantum channel constructed from mode entangled states

We present a setup for direct total quantum teleportation of two-particle mode entangled state through the four-photon quantum channel constructed as a tensor product of two two-photon mode entangled states. The quantum channel as a tensor product of two two-photon mode entangled states can be more easily generated on compared with other complex multi-particle quantum channels. Four modes of the mode entangled state are directly transferred to other spatial four modes with 25% probability of success. A Bell state measurement with four beam splitters and two pairs of detectors is accomplished in coincidence basis in the teleportation protocol.
