Quantum imaging: enhanced image formation using quantum states of light

We review recent research in the field of quantum imaging. Quantum imaging deals with the formation of images that possess higher resolution or better signal-to-noise characteristics than conventional images by making use of the coherence properties of quantum light fields. Quantum imaging also deals with indirect imaging methods such as ghost imaging, in which image information is conveyed not by a single light field but by the correlations between two separate light fields. In this contribution we concentrate primarily on recent results in the area of ghost imaging.
