“…There have been many studies previously published on the RSP of arbitrary three-qubit state. [44][45][46][47] In 2016, Falaye et al [44] put forward a JRSP protocol of three-qubit states via three tripartite GHZ entangled states in noisy quantum channel, by putting some special cases into consideration, in which the success probability could be ameliorated to 1. In 2018, Sun et al [45] studied the effects of noise on two DRSP protocols of an arbitrary three-qubit state, where χ state and Brown state were used as the quantum channel, respectively.…”

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.
