Long-distance teleportation based on a selected receiver in a quantum network

Abstract Quantum networks are useful for global communication. A new multi-hop scheme of single unitary transformation method (SUTM) is proposed for long-distance teleportation of an unknown W state in a quantum network. All the measurement outcomes are sent to the selected receiver independently. The initial quantum state can be recovered by a corresponding local operation. The probability of successful teleportation can reach 1 without auxiliary particles. Our scheme is superior to the hop-by-hop method owing to lower delays.
