Abstract

There is a great deal of interest in highly sensitive sensing technology that utilizes the quantum entanglement of quantum light. Light wave sensing based on the quantum illumination theory is expected to be used outdoors with atmospheric disturbances. For the realization of such technology, it is extremely important to know the fundamental properties of quantum light propagation under various atmospheric conditions. In this study, we first investigated the propagation characteristics of laser light in fog. Next, we investigated the effects of fog on the quantum properties of single-mode squeezed light. It was found that when the fog density increases, not only the light energy is attenuated, but also the noise is superimposed on the intensity distribution. It was also found that the effect of fog on the squeezed light is mainly energy attenuation.
