Abstract

Motivated by multi-step quantum teleportation of single-qubit states and two-qubit states with entanglement swapping, we present a small scale quantum network communication scheme based on entanglement of Bell states. In this scheme, it contains certain number of single-qubit quantum source nodes that teleport unknown quantum states to other nodes in the network in the multi-teleport fashion where every intermediate node can pass on any of its received quantum information to others via multi-step quantum teleportation. It makes legal nodes more convenient than any other previous schemes to transmit unknown quantum states to unknown participants in practical applications. The security of this scheme is based on the securely-shared quantum channels between all nodes.

Research Paper: Multi-hop Quantum Teleportation Scheme of the 6-Qubit Entangled State by Intermediate Nodes with the Best Efficiency

Negin Fatahi

Quantum multi-hop teleportation is important in the field of quantum communication. In this paper, we proposed a Multi-hop quantum teleportation scheme of the 6-qubit entangled state. In the proposed scheme, the sender teleports the desired information by transmitting a 6-qubit entangled quantum state to the receiver through the N intermediate nodes between the source node and destination node. Therefore, the sender and receiver are not in direct connection with each other, and the information is teleported in Multi-hop between the N neighbor nodes. Also, in this scheme, the 7-qubit entangled states as quantum channels are shared between neighbor nodes. Always, teleportation processes over long distances are problematic because of the existence of the environmental noise which is almost inescapable and adversely affects the entangled quantum channel. This scheme explains the quantum teleportation between N nodes in N-1 steps and it is suitable for teleportation processes over long distances. Also, we calculate the efficiency of this scheme and indicate the advantages of this protocol.

Multi-hop teleportation ofN-qubit state via Bell states

Negin Fatahi

Multi-hop teleportation is a quantum teleportation scheme for transferring quantum states on a large scale. In this paper, a new multi-hop teleportation protocol is investigated for transferring arbitrary N-qubit states between M-neighbor nodes. In this scheme, intermediate nodes are connected with each other by symmetric entangled Bell states as quantum channels. First, one-hop teleportation of single-qubit, two-qubit and N-qubit states are introduced, then this method is generalized to two-hop and multi-hop teleportation for N-qubit. Also, we calculate the efficiency of this scheme.

Multi-hop teleportation in a quantum network based on mesh topology

Xiaoqin Gao, Zaichen Zhang, Bin Sheng

In this paper, we propose a mesh-topology-based multi-hop teleportation scheme for a quantum network. By using the proposed scheme, quantum communication can be realized between two arbitrary nodes, even when they do not share a direct quantum channel. Einstein–Podolsky–Rosen pairs are used as quantum channels. The source node (initial sender) and all intermediate nodes make Bell measurements independently. They send the results to the destination node (final receiver) by classical channels. The quantum state can be determined from the Bell measurement result, and only the destination node is required for simple unitary transformation. This method of simultaneous measurement contributes significantly to quantum network by reducing the hop-by-hop transmission delay.

Multi-level hierarchical multi-hop quantum teleportation based on GHZ-Bell states

She-Xiang Jiang, Qi-Ke Zhang

Abstract The development of quantum communication technologies has made the efficient transmission and processing of quantum states increasingly important. This paper first introduces a traditional multi-hop quantum teleportation scheme based on simultaneous entanglement swapping(SES). In this scheme, different quantum channels are used for odd-hop and even-hop quantum teleportation, respectively. The specific quantum communication processes of two-hop, three-hop, and four-hop are introduced in turn, and the transmission law of n-hop quantum teleportation is summarized. On this basis, a multi-level hierarchical simultaneous entanglement swapping(MHSES) scheme for multi-hop quantum teleportation is further proposed, which is achieved by dividing the multi-hop quantum network into multiple segments with multiple levels of processing. In each level, the intermediate nodes only need to send the measurement results to the nodes at the end of the segment, thus greatly reducing the forwarding of classical information. IBM Qiskit was used to simulate the operation of these two schemes in ideal and noisy environments. Finally, the proposed scheme is compared with the existing conventional quantum teleportation schemes, and the results show that the proposed scheme achieves better results in terms of reduced classical resource consumption and reduced time delay.

Multi-hop teleportation of unknown qutrit state based on the GHZ channels

Yi Ding, Min Jiang

The combination of quantum communication technology and wireless networks brings a flexible and secure communication method, which adapts to a more complex network environment. In this paper, a new multi-hop teleportation scheme is investigated for transferring an unknown qutrit state between distant parties. The intermediate nodes are introduced and linked with each other via partially entangled Greenberger-Horne-Zeilinger (GHZ) states as quantum channels. In this multi-hop teleportation protocol, the source node and all the intermediate nodes can perform the entanglement measurement and transmit the measurement results simultaneously. Furthermore, we find the relationship between the measurement results and the receiver’s state, which is given as the matrix form. Compared with previous protocols for multi-hop transmission, our scheme can reduce the transmission delay and save the transmission overhead.

Network Coding-Based Communications via the Controlled Quantum Teleportation

Inspired by the structure of the network coding over the butterfly network, a framework of quantum network coding scheme is investigated, which transmits two unknown quantum states crossly over the butterfly quantum system with the multi-photon non-maximally entangled GHZ states. In this scheme, it contains certain number of entanglement-qubit source nodes that teleport unknown quantum states to other nodes on the small-scale network where each intermediate node can pass on its received quantum states to others via superdense coding. In order to transmit the unknown states in a deterministic way, the controlled quantum teleportation is adopted on the intermediate node. It makes legal nodes more convenient than any other previous teleportation schemes to transmit unknown quantum states to unknown participants in applications. It shows that the intrinsic efficiency of transmissions approaches 100% in principle. This scheme is secure based on the securely-shared quantum channels between all nodes and the quantum mechanical impossibility of local unitary transformations between non-maximally entangled GHZ states. Moreover, the generalized scheme is proposed for transmitting two multipartite entangled states. DOI: http://dx.doi.org/10.11591/telkomnika.v11i2.2031
