“…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.

“…In RSP, the sender can transmit a known state to the receiver and it has less classical communication cost than QT. In order to improve the security in RSP, a variety of schemes of controlled RSP (CRSP), [30][31][32][33][34][35][36][37] joint RSP (JRSP), [38][39][40][41][42][43][44][45][46][47][48] controlled bidirectional RSP (CBRSP), [49][50][51][52][53] and controlled JRSP (CJRSP) [54][55][56] are presented.…”

Recently, a scheme for deterministic remote preparation of arbitrary multi-qubit equatorial states was proposed by Wei et al. [Quantum Inf. Process. 17 70 (2018)]. It is worth mentioning that the construction of mutual orthogonal measurement basis plays a key role in quantum remote state preparation. In this paper, a simple and feasible remote preparation of arbitrary n-qubit equatorial states scheme is proposed. In our scheme, the success probability will reach unit. Moreover, there are no coefficient constraint and auxiliary qubits in this scheme. It means that the success probabilities are independent of the coefficients of the entangled channel. The advantage of our scheme is that the mutual orthogonal measurement basis is devised. To accomplish the quantum remote state preparation (RSP) schemes, some new sets of mutually orthogonal measurement basis are introduced.
