“…And our protocol is not sensitive to collusive attacks (or called inside attacks) according to the above security analysis. Two-photon entangled states and single-photon states are used as the information carriers in our protocol, they can be prepared and controlled [47,48,49,50,51] even at a great distance. And photon states are also of great use in other fields, such as quantum computation [52,53,54,55] and quantum simulation [56,57].…”

We propose a high-efficiency three-party quantum key agreement protocol, by utilizing two-photon polarization-entangled Bell states and a few single-photon polarization states as the information carriers, and we use the quantum dense coding method to improve its efficiency. In this protocol, each participant performs one of four unitary operations to encode their sub-secret key on the passing photons which contain two parts, the first quantum qubits of Bell states and a small number of single-photon states. At the end of this protocol, based on very little information announced by other, all participants involved can deduce the same final shared key simultaneously. We analyze the security and the efficiency of this protocol, showing that it has a high efficiency and can resist both outside attacks and inside attacks. As a consequence, our protocol is a secure and efficient three-party quantum key agreement protocol.Quantum communication provides an unconditionally secure way for the transmission of information, by exploiting the principles in quantum mechanics. In recent decades, this field gains much attention of researchers all over the world. There are many important branches of quantum communication for different tasks, such as quantum key distribution (QKD) [1,2,3], quantum secure direct communication (QSDC) [4,5,6,7,8,9,10,11,12], quantum secret sharing (QSS) [13], and so on. QKD supplies a secure way for two remote legitimate parties to create a private key [1,2,3]. The parties in QKD can detect the eavesdropper, say Eve, if she monitors their quantum channel, by picking up a subset of their outcomes obtained with two nonorthogonal measuring bases to check eavesdropping. They can then discard the outcomes when they find Eve. Far different from QKD, QSDC gives an absolutely secure approach for two parties to transmit their secret message directly, without producing the private key in advance. The first QSDC scheme was proposed by Long and Liu [4] and it exploits the properties of Bell states and uses a block transmission technique in 2002. Subsequently, Deng, Long, and Liu [5] clarified the standard criterion for QSDC explicitly in 2003, and they proposed an important two-step QSDC protocol by using the Einstein-Podolsky-Rosen photon pair blocks . Recently, these two-step QSDC protocols [4,5] were experimentally implemented by two groups [6,7]. In 2004, Deng and Long [8] introduced the first QSDC protocol based on a sequence of single photons, called quantum one-time pad scheme which has been recently experimentally demonstrated by Hu et al. [9] in a noisy environment with frequency coding. In 2017, Wu et al. [10] proposed a high-capacity QSDC protocol with two-photon six-qubit hyperentangled states. QSS is used to share a secret key among some agents of a boss [13], in which the agents can reconstruct the secret if and only if they collaborate. QSS has a higher requirement than QKD because a potentially dishonest agent may injure the benefit of the boss. The inside attacks will increase largely the diffic...

“…Thus, the cost of classical communication is lower. For this reason, considerable effort has been devoted to the study of this technique from researchers, producing a number of schemes [20]- [27] and many variants of RSP schemes, such as controlled RSP (CRSP) [28]- [30], controlled bidirectional RSP (CBRSP) [31]- [33], and joint RSP (JRSP) [34], [35]. However, these schemes only focus on one-way directional or bidirectional quantum state preparation.…”

In this paper, a scheme for cyclic hybrid double-channel quantum communication is proposed by using the product state of three Bell states and three Greenberger-Horne-Zeilinger (GHZ) states as the quantum channel. It shows that Alice teleports a single-qubit state to Bob and prepares a single-qubit state for Charlie, Bob teleports a single-qubit state to Charlie and prepares a single-qubit state for Alice, while Charlie teleports a single-qubit state to Alice and prepares a single-qubit state for Bob. The quantum channel is constructed by using Hadamard (H) and Controlled-NOT (CNOT) operations. Participants reconstruct the desired states by performing Bell-state measurements, single-qubit measurements, and unitary transformations. Compared with existing schemes, this new scheme improves the efficiency and capacity of quantum communication because it constructs a cyclic and bidirectional quantum communication and simultaneously supports two communication protocols, quantum teleportation and remote state preparation. Only single-qubit measurements, two-qubit measurements, and basic unitary transformations are utilized in the scheme, so our operation complexity is lower than others. Thus, the scheme is likely to be implemented through physical experiments in the future. Besides this, we discuss the impact of noisy environments (amplitude-damping, phase-damping noise, bit-flip noise, and phase-flip noise) in the scheme and calculate the fidelities of the output states. It is demonstrated that the fidelities only depend on the coefficients of the initial state and the decoherence rate.

Linear-optical-based quantum information processing has attached much attention since photon is an ideal medium for transmitting quantum information remotely. Until now, there are some important works in quantum state remote preparation, the method for reconstructing quantum state deterministically via linear optics. However, most of the methods are protocols to prepare single-qubit states remotely via linear-optical elements. In this article, we investigate the methods to prepare two-qubit hybrid states remotely. We present a deterministic remote state preparation scheme for an arbitrary two-qubit hybrid state via a hyperentangled Bell state, resorting to linear-optical elements only. The sender rotates the spatial-mode state and polarization state of the hyperentangled photon respectively in accordance with his knowledge of the two-qubit hybrid state, and the receiver can reconstruct the original two-qubit hybrid state by applying appropriate recovery operations. Moreover, we discuss the remote state preparation scheme for the two-qubit hybrid state via partially hyperentangled Bell state.
