“…Therefore, it has overwhelming advantages in the information security, and its development is extremely rapid. Nowadays, the research of quantum cryptography is extremely active in the fields of quantum key distribution (QKD) [1,2,3,4], quantum secret sharing (QSS) [5,6,7] and quantum secure direct communication (QSDC) [8,9]. Unlike the QKD protocols, quantum key agreement (QKA) [10,11,12,13,14] is a new important branch that each participant plays an equivalent role on generating the shared key.…”

With the emergence of the multi-party quantum key agreement, the participant attack has attracted great attention, since it is a destructive attack which is easier to obtain the effective information than the external attack. In this paper, a new multi-party quantum key agreement protocol with six-qubit cluster states which has the verification function is put forward. At first, a verifiable distributor is introduced to distribute the remaining information of six-qubit cluster states to any two adjacent participants after preserving a part. Next, once the participants verify the correctness of the received information with the properties of six-qubit cluster states under the X-basis, the cluster states are used as the quantum resource to perform the X operation in the participant operation phase. Finally, it can not only verify the correctness of the recovered shared key, but also guarantee its simultaneity through the trusted design combiner and homomorphic hash function. Furthermore, the security analysis shows that the new protocol can resist the external and internal attacks. And it's proved that our protocol is meaningful through the comparation analysis.

“…Quantum entanglement is very crucial in quantum cryptography, and there are many applications of entanglement in quantum communication schemes, including quantum secure direct communication [1], quantum secret sharing [2], quantum teleportation [3], [4] and remote state preparation (RSP) [5], [6]. RSP is the teleportation of a known state.…”

We present an asymmetric controlled bidirectional remote preparation scheme under the control of Charlie, where Alice transmits an arbitrary single-qubit equatorial state to Bob and Bob transmits an arbitrary three-qubit equatorial state to Alice. First, the quantum channel is constructed by using Hadamard (H) and CNOT operations. Second, we consider our scheme in the noiseless environment and construct the appropriate measurement bases. In addition, the participants can recover the prepared states through implementing the corresponding recovery operations determinately. Third, we discuss our scheme in five types of noisy environments (amplitude-damping, phase-damping, bit-flip, phase-flip, and depolarizing noisy environment). The fidelities of the output states are calculated, which depend on the coefficients of the prepared states and the decoherence rates. Finally, some discussions and conclusions are given. Compared with previous schemes, our scheme does not need additional operations or auxiliary qubits. So it is slightly more efficient. INDEX TERMS Asymmetry, controlled bidirectional remote preparation, noisy environment, fidelity.
