“…Therefore, quantum cryptography is attracting more and more attention from both industry and academia. Up to date, various quantum communication protocols have been presented by scholars and engineers, such as quantum key distribution (QKD), [3][4][5] quantum secure direct communication (QSDC), [6][7][8] quantum secret sharing (QSS), [9][10][11] quantum teleportation (QT), [12,13] remote state preparation (RSP), [14,15] and quantum signature (QS). [16,17] As a significant branch of quantum cryptography, quantum dialogue (QD) allows two participants to exchange their secret message simultaneously, which is also known as bidirectional quantum secure direct communication (BQSDC).…”

Quantum system is inevitably affected by the external environment in the real world. Two controlled quantum dialogue protocols are put forward based on logical χ-type states under collective noise environment. One is against collective-dephasing noise, while the other is against collective-rotation noise. Compared with existing protocols, there exist several outstanding advantages in our proposed protocols: Firstly, the χ-type state is utilized as quantum channels, it possesses better entanglement properties than GHZ state, W state as well as cluster state, which make it difficult to be destroyed by local operations. Secondly, two kinds of logical χ-type states are constructed by us in theory, which can be perfectly immune to the effects of collective noise. Thirdly, the controller can be offline after quantum distribution and permission announcement, without waiting for all the participants to complete the information coding. Fourthly, the security analysis illuminates that our protocols can not only be free from the information leakage, but also resist against the intercept-and-resend attack, the entanglement-and-measure attack, the modification attack, the conspiring attack, and especially the dishonest controller’s attacks.

“…If and only if all the senders agree to collaborate, the receiver can reconstruct the original quantum state. In particular, some authors have discussed JRSP of fourqubit entangled states, including four qubit clustertype state [39,[51][52][53] and fourqubit ⟩ χ | type state [54].…”

We present two schemes for the joint remote state preparation (JRSP) of an arbitrary tripartite four-qubit entangled state with complex coefficients via four and two three-qubit GHZ states as the quantum channel, respectively. In these schemes, the two senders share the original state which they wish to help the receiver remotely prepare. To complete the JRSP schemes, some novel sets of mutually orthogonal basis vectors are introduced. It is shown that, only if the two senders collaborate with each other, and perform projective measurements under a suitable measuring basis on their own qubits respectively, can the receiver reconstruct the original state by means of some appropriate unitary operations. We demonstrate, in our both schemes, the total success probability of the JRSP can reach 1. Moreover, compared with the first scheme in this paper, the advantage of the second scheme is that the entanglement resource can be reduced.
