摘　　要：针对图像信息的远距离安全传输与重构问题,给出了一种利用实际商用光纤的量子密钥加密单像素成像实验方案,完成了目标物体32km的远距离重构。采用量子密钥分别对单像素成像的桶探测值和散斑值进行加密,结果表明:在不解密情况下,两种不同加密方式都无法重构目标物体的图像,表现出良好的加密效果;在解密情况下,两种加密方式的重构图像均随着量子密钥误码率减小,峰值信噪比增大,重构图像质量随之提高。相同误码率情况下,两种加密方式的重构图像质量基本接近,但散斑加密方式消耗大量的量子密钥,采用桶探测值加密方式更有利于实际应用。To resolve the problem of long-distance secure transmission and reconstruction of image information,an experimental scheme of quantum key encrypted single pixel imaging using actual commercial optical fiber is given in the paper to complete the long-distance(32km) reconstruction of the target object.The bucket detection value and speckle value of single pixel imaging are encrypted by quantum key respectively.The results show that the two different encryption methods cannot reconstruct the image of the target object without decryption,showing good encryption effect.In the case of decryption,the reconstructed images of the two encryption methods both decrease with the quantum key error rate,the peak signal-to-noise ratio increases,and the reconstructed image quality increases accordingly.With the same bit error rate,the reconstructed image quality of the two encryption methods is basically similar to each other,but the speckle encryption method consumes a lot of quantum keys,and the bucket detection value encryption method is more conducive to practical application.
