We propose a remote state preparation scheme working in noisy environment via one intermediate node. Firstly, we report the remote preparation of an arbitrary single-qubit state with one intermediate node in ideal environment. Afterwards, we investigate the influence of four kinds of representative noises that are commonly encountered in practical applications of quantum communication protocols. Detailed analysis indicates that the fidelities of the output state rely on the coefficients of the prepared state and the decoherence rate. The turning point is lambda = 0.5 in both the bit-flip and phase-flip noisy channels. The fidelity in the depolarizing channel is related with the decoherence rate, and independent with the phase parameters. (C) 2019 Elsevier B.V. All rights reserved.
