A multi-hop teleportation protocol of arbitrary four-qubit states through intermediate nodes
Binayak Samadder Choudhury, Soumen Samanta · International Journal of Quantum Information · 2018
Teleportation processes over long distances become affected by the almost inevitable existence of noise which interferes with the entangled quantum channels. In view of this, intermediate nodes are introduced in the scheme. These nodes are connected in series through quantum entanglement. In this paper, we present a protocol for transferring an entangled four-particle cluster-type state in an integrated manner through the intermediate nodes. Its efficiency and advantage over the corresponding part by part teleportation process is discussed.
