提出了一种在量子计算机上水印和恢复未标记灰度图像的方案。从量子图像-水印对的经典传统或非量子版本中提取迄今为止无法访问的数据，使用这些数据，使用两个量子子电路来执行两层转换，包括以下更改：1在封面图像的量子副本的预定子区域中嵌入可见和半透明的水印徽标；以水印信号所指示的方式修改封面图像的剩余内容，使水印图像上产生的扭曲不容易被识别。对图像-水印对以及获取标记和未标记图像所需的各种子电路的经典仿真表明，当必要的量子硬件实现时，所提出的方案是可行的。该提案推进了现有文献，旨在保护量子资源免受未经授权的复制，并在发生争议的情况下确认其所有权，从而导致量子信息的商业应用。
A scheme is proposed to watermark and recover unmarked greyscale images on quantum computers. The hitherto inaccessible data from a quantum image-watermark pair is extracted from their classical conventional or non-quantum versions using which two quantum sub-circuits are used to execute the two-tier transformations comprising of changes that: 1 embed a visible and translucent watermark logo in a predetermined sub-area of the quantum replica of the cover image; 2 modify the remaining content of the cover image in a manner dictated by the watermark signal, so that the resulting distortions on the watermarked image are not easily discernible. Classical simulations of the image-watermark pairs and the various sub-circuits required to obtain the marked and unmarked images demonstrate the feasibility of the proposed scheme when the necessary quantum hardware are realised. The proposal advances available literature geared towards safeguarding quantum resources from unauthorised reproduction and confirmation of their proprietorship in cases of dispute thereby leading to commercial applications of quantum information.
