<p>Quantum ghost imaging is the protocol that uses entanglement to obtain images of an object, which was realized by T.B. Pittman et al. In quantum ghost imaging, one of the two entangled lights is illuminated to the object, and the other is illuminated directly to the detector. Then, the image of the object is generated by correlating the intensity of these lights. Thus, compared to ordinary cameras, it is less affected by noise. However, it takes a long time to obtain the image of the object because it requires many times of illuminations of light. Therefore, in this study, we consider quantum ghost imaging that illuminates multiple positions simultaneously. We evaluate the effect of reducing the time to obtain the image by multiple positions illumination by the peak signal-to-noise ratio performance of quantum ghost imaging depending on the number of illuminated positions N and transmissivity η. Then we clarify that large N realizes better performance than small N when the attenuation is severe but a value of N that is too large degrades the performance when the attenuation is low.</p>
