Image steganography technique is widely used to realize the secrecy transmission. Although its strategies on classical computers have been extensively researched, there are few studies on such strategies on quantum computers. Therefore, in this paper, a novel, secure and keyless steganography approach for images on quantum computers is proposed based on Moir´ e pattern. Algorithms based on the Moir´ e pattern are proposed for binary image embedding and extraction. Based on the novel enhanced quantum representation of digital images (NEQR), recursive and progressively layered quantum circuits for embedding and extraction operations are designed. In the end, experiments are done to verify the validity and robustness of proposed methods, which confirms that the approach in this paper is effective in quantum image steganography strategy.

程序仿真了瑞利信道，分析和大量实测表明，多径效应使接收信号包络变化接近瑞利分布。在典型移动通信中，衰落深度达30dB左右，衰落速率约30~40次/秒。(Rayleigh channel simulation procedures, analysis and extensive test shows that the received signal multipath effect changes in the envelope close to the Rayleigh distribution. In a typical mobile communication, fading depth of about 30dB, the decline rate of about 30 to 40 times/sec.)
