“…In the past decades, several branches of RSP have emerged, such as deterministic remote state preparation (DRSP) [22][23][24][25], deterministic joint remote state preparation (DJRSP), controlled remote state preparation (CRSP) [26][27][28] and joint remote state preparation (JRSP) [29][30]. In RSP since the preparer holds all information about the state to be prepared, if he is not faithful, the protocol will become insecure.…”

We propose a scheme for deterministic remote preparation of an arbitrary two-qubit state via a relay node.Afterwards, we investigate how the scheme is influenced by the noise type, the initial state to be remotely prepared, and the decoherence rate. We find that the fidelity is symmetrical with the line () in bit-flip and phase-flip channels.In addition, the fidelity decreases with the increase of decoherence rate in the amplitude-damping and phase-damping channels. We also compare it with other RSP schemes. Since only Bell pairs work as the quantum channels, it makes our RSP scheme more available and feasible.

“…So far, the research of multiparty RSP via non-maximally entangled channels has made dramatic progress. [26][27][28][29][30][31][32] Recently, Chen et al [28] put forward the controlled RSP of two-qubit state using an eight-qubit partially entangled channel. In 2017, a multiparty RSP scheme was introduced in Ref.…”

Due to the unavoidable interaction between the quantum channel and its ambient environment, it is difficult to generate and maintain the maximally entanglement. Thus, the research on multiparty information transmission via non-maximally entangled channels is of academic value and general application. Here, we utilize the non-maximally entangled channels to implement two multiparty remote state preparation schemes for transmitting different quantum information from one sender to two receivers synchronously. The first scheme is adopted to transmit two different four-qubit cluster-type entangled states to two receivers with a certain probability. In order to improve success probabilities of such multicast remote state preparation using non-maximally entangled channels, we put forward the second scheme, which deals with the situation that is a synchronous transfer of an arbitrary single-qubit state and an arbitrary two-qubit state from one sender to two receivers. In particular, its success probability can reach 100% in principle, and independent of the entanglement degree of the shared non-maximally entangled channel. Notably, in the second scheme, the auxiliary particle is not required.

“…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.…”

Efficient scheme for remote preparation of arbitrary n-qubit equatorial states

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.
