Efficient and general quantum image representation and preparation are the precondition of quantum image processing. The multi-mode quantum image representation is compatible with many important color modes. Studying image preparation and image processing will help to further improve the universality of quantum image on different application fields. In this paper, we improve the multi-mode quantum image representation to reduce the difficulty of entanglement preparation. We give a detailed image preparation process and algorithm based on this proved representation. Then, to reduce the number of Not-gates in preparation circuits, the optimal preparation is proposed. Furthermore, we give the reproduction circuit based on these preparations. The preparation and reproduction experiments are performed on the IBM Quantum lab platform. The circuits and the Bell-state statistic histograms of the measurement collapse are given. The results show that the preparations and reproduction are correct and efficient.

高效、通用的量子图像表示和准备是量子图像处理的前提。多模式量子图像表示与许多重要的颜色模式兼容。研究图像准备和图像处理将有助于进一步提高量子图像在不同应用领域的通用性。在本文中，我们改进了多模量子图像表示以降低纠缠制备的难度。我们基于这个证明的表示给出了详细的图像准备过程和算法。然后，为了减少准备电路中非门的数量，提出了最佳准备。此外，我们给出了基于这些准备的再现电路。制备和复制实验在 IBM Quantum 实验室平台上进行。给出了测量崩溃的电路和贝尔状态统计直方图。结果表明制备和繁殖是正确和有效的。
