Multimode entangled states of light in fantom imaging, multiplexing and background reduction

In the report we discuss four-mode entangled states of light in fantom imaging. We consider application of bright Bell states and light states created via optical parametric processes. The latter enable observing 3 fantom images, and Bell states allow reducing the background noise, which is present in classical scheme of fantom image observation. We show that the application of the reduction method allows to improve the quality of the reconstructed image, taking into account the correlation of fantom images.
