摘要(Abstract)：

为了提高图像秘密共享的安全性和高效性，提出一种基于随机网格的量子图像视觉秘密共享方案，并设计相应的量子线路；通过对已经分块的秘密图像和载体图像进行异或运算来构造随机网格图像，利用最低有效位替换算法将含有秘密图像信息的随机网格图像隐藏到载体图像中，含有秘密图像信息的载体图像被秘密共享；在恢复阶段，所有持有载体图像的参与者共同提供各自的图像，先恢复出随机网格图像，再将分块随机网格图像与对应分块载体图像进行异或运算，得到分块秘密图像，最终拼接出完整的原始秘密图像；在MATLAB、 IBM Qiskit平台上对该视觉秘密共享方案进行仿真实验。结果表明，本文中所提方案同时实现了随机网格图像恢复简单的特性和量子算法的高效性，相较于其他图像秘密共享方案，该方案的量子算法复杂度呈指数级降低。
