- Аннотация: We theoretically show that application of multipartite entangled quantum states opens new possibilities in ghost imaging in the spatial and temporal domains. To demonstrate these possibilities, we use the four-partite entangled quantum states: the bright polarization- entangled Bell ones and the four-partite entangled ones produced in the process of parametric amplification at low pumping that includes two coupled parametric interactions and have different frequencies. Ghost imaging in the spatial domain is considered in detail. It is shown that in the case of using the four-partite entangled states three ghost images can be simultaneously obtained. In this case the object is illuminated by radiation of one frequency, while the ghost images are reconstructed from fields with different frequencies. In other words, the multiplexing (multiplication) of the image takes place. However, in the scheme under consideration and in all schemes used it is necessary to subtract the background from measurement of the spatial correlation function to reconstruct the ghost image. It is shown that this disadvantage of reconstruction of the images can be eliminated when bright polarization- entangled states are used in scheme. It should be emphasized that in these examples of ghost imaging the quantum properties of light are of fundamental importance.
