Entangled photons, generated by spontaneous parametric down-conversion from a second-order nonlinear crystal, present a rich potential for imaging and image-processing applications. Since this source is an example of a three-wave mixing process, there is more flexibility in the choices of illumination and detection wavelengths and in the placement of object(s) to be imaged. Moreover, this source is entangled, a fact that allows for imaging configurations and capabilities that cannot be achieved using classical sources of light. We have established a theory of image formation using this source and are investigating a number of imaging and image-processing configurations that can be realized. One of these configurations permits the remote extraction of holographic information via a technique we have termed "quantum holography."
