“…Deterministic RSP has the successful probability of one hundred percent [9][10][11]. It could be fulfilled via Cluster-type state [12], χ state [10], Brown state [13], entangled six-qubit state [14] and so on. The preparation of special states have been studied, such as pure and mixed polarization states [15], four-particle entangled W-state [16,17], arbitrary n-qubit equatorial states [18,19], entangled Cluster-type state [20,21], continuous variable RSP [22] and asymmetric five-party three-qubit entangled state [23].…”

Joint remote state preparation is an important method to transmit quantum information with more senders and higher security. In this paper, we present a deterministic joint remote state preparation scheme in multi-hop network with two senders and $N$ intermediate parties, using only projective measurements and recovery operations. We describe the scheme under the framework of density matrix to investigate the performance of the scheme in noisy environment. The relation of fidelity, noise rate and the number of intermediate nodes is given for three types of noise. It is revealed that the average fidelity attains its minimum when the noise rate is at the most uncertain point, decreases monotonically as the number of intermediate nodes increases. However, in some special cases, the average fidelity of the multi-hop scheme is greater than some existing one step joint remote state preparation scheme.

“…In 2018, Wei et al [39] gave an efficient DRSP scheme for preparing an arbitrary n-qubit equatorial state via multiple two-qubit maximally entangled states. In 2020, Zha et al [40] proposed two DRSP protocols, where an arbitrary four-qubit cluster state could be prepared using two Bell states. In these schemes, the ideal channels were used.…”

We propose a novel scheme for remote state preparation of an arbitrary three-qubit state with unit success probability, utilizing a nine-qubit cluster-GHZ state without introducing auxiliary qubits. Furthermore, we proceed to investigate the effects of different quantum noises (e.g., amplitude-damping, phase-damping, bit-flip and phase-flip noises) on the systems. The fidelity results of three-qubit target state are presented, which are usually used to illustrate how close the output state is to the target state. To compare the different effects between the four common types of quantum noises, the fidelities under one specific identical target state are also calculated and discussed. It is found that the fidelity of the phase-flip noisy channel drops the fastest through the four types of noisy channels, while the fidelity is found to always maintain at 1 in bit-flip noisy channel.

“…[34] Thus, many authors proceeded to focus on RSP of transmitting cluster-type states in recent years. [35][36][37][38][39][40][41] For example, by two non-maximally entangled GHZ-type states, Wei et al [37] presented an efficient RSP scheme of preparing a four-qubit entangled cluster-type state. However, for above-mentioned schemes, the requirements about the low complexity and synchronous diverse information transmission are not satisfied.…”

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.
