Secure Unknown Quantum State Transmission Using GHZ Class State via Collective Noise Channel

Abstract

Recently, Dong et al. [Commun. Theor. Phys. 54 (2010) 269-272] proposed two protocols for transmitting unknown quantum states over the collective-dephasing noise channel using Greenberger-Horne-Zeilinger (GHZ) state. This work further extends Dong et al.'s protocols over an insecure channel, in which malicious users attempt to reveal useful information from the transmitted quantum states. Moreover, a secure unknown single-photon transmission protocol will be proposed for collective-rotation noise channel, over which Dong et al.'s work fails to show their non-straight forward constructions.

Unknown State Transmission Using GHZ States via Collective Noise Channel

Li Dong, Xiu Xiao-Ming, Gao Ya-Jun +1 more

Two protocols for transmitting an unknown single-photon state and an unknown non-maximally entangled EPR state are presented by using the quantum channel of three-phonton GHZ (Greenberger–Horne–Zeilinger) state, which can be realized with unitary success probability when collective noise is taken into account. The protocols can also be generalized to transmit multi-photon state or to realize quantum communication in collective noise channel.

Improvement of Security of Three-Party Quantum Secure Direct Communication Based on GHZ States

Man Zhong-Xiao, Yun‐Jie Xia

A protocol for three-party quantum secure direct communication based on Greenberger–Horne–Zeilinger (GHZ) states was recently proposed by Jin et al. [Phys. Lett. A 354 (2006) 67] By analysing the protocol we find some security loopholes, e.g. one bit of secret messages of a party (Alice in the original paper) can always be leaked straight to the public without any eavesdropping. These problems suggested previously are discussed and possible solutions are presented to improve the security of the original protocol.

Multiparty quantum secret sharing based on GHZ states

Tzonelih Hwang, Cheng-Chieh Hwang, Chuan-Ming Li

Gao (2009 Commun. Theor. Phys. 52 421–4) has proposed an efficient multiparty quantum secret sharing (MQSS) with two-photon three-dimensional Einstein–Podolsky–Rosen (EPR) pairs. This work shows that a similar idea can also be used to construct an MQSS using the Greenberger–Horne–Zeilinger (GHZ) states. Compared to other MQSSs using GHZ-related states, the newly proposed protocol is more efficient in the aspect of qubit utilization.

Cryptanalysis of quantum secret sharing based on GHZ states

Xiao-Fen Liu, Ri-Jing Pan

In a recent paper (Hwang et al 2011 Phys. Scr. 83 045004), a subtle quantum secret sharing (QSS) protocol was proposed. One major advantage of this protocol is its high efficiency; that is, it is more efficient than other QSS protocols using the Greenberger–Horne–Zeilinger states. However, we analyzed the security of this protocol and found that it is insecure for one agent who may deduce half of the information about the deal's secret directly just by his/her piece of secret. Finally, a feasible improvement of this QSS protocol is put forward.

Multiparty-controlled teleportation with generalised GHZ states in quantum communication network

Xiaoqing Tan, Lianxia Jiang, Junpeng Hu

A multiparty-controlled teleportation (M-CT) scheme for securely teleporting an arbitrary unknown single-qubit state by using generalised Greenberger-Horne-Zeilinger (GHZ) states is presented in this paper, i.e., a sender, Alice, transmits an arbitrary single-qubit state to a distant receiver, Bob, under approving by all N controllers Charliei(i = 1, 2, …, N) in a quantum communication network. It is proved feasibly and easily to realise by quantum entanglement. The security of proposed scheme is also discussed. We make sure of the security of the quantum channel between the parties by decoy states. This scheme also can be used to share a quantum secret information in quantum secret sharing.
