“…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...

By blending the ideas of controlled teleportation, bidirectional teleportation and remote implementation of quantum operations, we investigate the bidirectional transmission of quantum operations under the control of one supervisor. Firstly, we provide a method for generating a class of multi-particle entangled states, including ﬁve-particle and seven-particle entangled states, using a nine-particle entangled state as an example. Then using our constructed ﬁve-particle entangled state as a quantum channel, we propose a new controlled bidirectional protocol for remotely implementing partially known quantum operations (PUQOs for short) of one qubit within the two restricted sets satisfying speciﬁc conditions. Subsequently, exploiting a nine-particle entangled state as the quantum channel, we extend it to the case of two-qubit quantum operations which come from eight restricted sets. Replacing two PUQO of two qubits by a PUQO of one qubit and a PUQO of two qubits, we put forward another new asymmetric controlled bidirectional protocol for remotely implementing PKQOs via a seven-particle entangled state as the quantum channel. In these protocols, by using universal recovered operations performed by the receivers, the senders can simultaneously exchange their PUQOs as long as the controller collaborates, where each PUQO acts on the corresponding unknown state owned by the remote recipient.
