Entanglement Teleportation Based on Noisy Port Based Teleportation

Abstract

Port-based teleportation(PBT) is one of variation of the original quantum teleportation, and is being used and explored in quantum information processing due to its various applications. This work delves into the realm of PBT, specifically when the resource state is subjected to Pauli noise from the environment. We characterise the noisy PBT protocol by describing as Kraus representation. Furthermore, we investigate the entanglement teleportation using the noisy PBT. We derive and investigate upper and lower bounds for the measure of entanglement of teleported unknown state. To achieve the above results, we have investigated the entanglement of two-qubit bipartite states through local Pauli channel. We derived the order of entanglement of two qubit states is preserved through Pauli channel, and also the boundaries of reduced entanglement through this channel.Comment: 10 pages, 4 figure
