A Group Quantum Communication Network Using Quantum Secret Sharing

Hongyang Ma, Zhongwen Guo

Quantum Key Distribution (QKD) is an ingenious application of quantum mechanics in information field. In this paper, it provides a novel algorithm for three group to establish a quantum key over a long distance. The slaves node send qubits to the master node in the first group and the three master nodes in the three groups share Greenberger-Horne-Zeilinger (GHZ), send qubits to one of slave nodes in group 3. Compared with the classical network architecture, it is proved in theory that an eavesdropper (Eve) invariably introduce errors within communication network if it wants to gain useful information. The nodes must find Eve to guarantee the security of the network.

Quantum Secret Broadcast for Wireless Quantum Networks

Tao Shang, Gang Du, Jianwei Liu

In wireless quantum networks, nodes communicate by means of pre-distribution for entangled pairs and relay path establishment for quantum teleportation. However, simple point-to-point communication seriously restricts the efficiency of quantum communication. Inspired by sharing idea of quantum secret sharing (QSS), which is based on three collaborative nodes with pre-shared GHZ (Greenberger-Horne-Zeilinger) states, we propose a quantum secret broadcast scheme to improve network performance. In a cluster net-work cored on three parties of QSS, three cluster heads with pre-shared GHZ states are senders, while cluster members are receivers. One cluster head encodes secret messages on auxiliary particles by performing certain operations on them with GHZ particles, then three cluster heads measure their own par-ticles and broadcast measurement results honestly. Based on the specific correlation of measurement results and secret messages, all receivers can re-cover the secret messages. Furthermore, to prevent eavesdropping, cluster heads can update an encoding key periodically. Analysis shows the proposed scheme is more efficient than previous schemes in wireless quantum net-works, especially when the number of receivers is larger. Besides, in the proposed scheme, attacks on quantum channel based on GHZ state can be detected, and eavesdroppers cannot recover messages correctly for lack of suitable decoding key.

Secure Quantum Secret Sharing Based on Reusable GHZ States as Secure Carriers

Song Jie, Zhang Shou

We show that a potential eavesdropper can eavesdrop whole secret information when the legitimate users use secure carrier to encode and decode classical information repeatedly in the protocol proposed by Bagherinezhad S and Karimipour V [Phys. Rev. A 67 (2003) 044302]. Then we present a revised quantum secret sharing protocol by using the Greenberger–Horne–Zeilinger state as secure carrier. Our protocol can resist Eve's attack.

Multi-User Quantum Wireless Network Communication Based on Multi-Qubit GHZ State

Zhenzhen Li, Gang Xu, Xiu‐Bo Chen +2 more

In this letter, a novel quantum wireless network communication (QWNC) scheme based on multi-qubit Greenberger-Horne-Zeilinger (GHZ) state is proposed. First, we deduce a general formula for the multi-user QWNC, which can greatly reduce the computational complexity and resource consumption. Second, a self-organized bilayer network architecture, as well as the corresponding communication protocol, are presented to ensure the rapid and steady transmission of quantum information. Finally, the advantages of our scheme are described based on the analysis of communication efficiency and security.

Efficient multiparty quantum secret sharing of secure direct communication

Jian Wang, Quan Zhang, Chaojing Tang

In this paper, we present an (n, n) threshold quantum secret sharing scheme of secure direct communication using Greenberger-Horne-Zeilinger state. The present scheme is efficient in that all the Greenberger-Horne-Zeilinger states used in the quantum secret sharing scheme are used to generate shared secret messages except those chosen for checking eavesdropper. In our scheme, the measuring basis of communication parties is invariable and the classical information used to check eavesdropping needs only the results of measurements of the communication parties. Another nice feature of our scheme is that the sender transmit her secret messages to the receivers directly and the receivers recover the sender's secret by combining their results, different from the QSS scheme whose object is essentially to allow a sender to establish a shared key with the receivers. This feature of our scheme is similar to that of quantum secret direct communication.
