Abstract

Ragy and Adesso argue that quantum discord is involved in the formation of a pseudothermal ghost image. We show that quantum discord plays no role in spatial light modulator ghost imaging, i.e., ghost-image formation based on structured illumination realized with laser light that has undergone spatial light modulation by the output from a pseudorandom number generator. Our analysis thus casts doubt on the degree to which quantum discord is necessary for ghost imaging.

摘要

拉吉和阿德索认为量子失协参与了赝热鬼成像的形成。我们表明，量子失协在空间光调制鬼成像中没有作用，也就是说，基于结构光照明显微镜的鬼成像形成，是通过由伪随机数发生器输出进行空间光调制的激光来实现的。因此，我们的分析对量子失协在鬼成像中的必要性提出了质疑。
