Abstract : The use of entangled states in a prospective standoff imaging sensor has been explored. Specifically, the question of whether enhanced performance (in terms of achievable resolution, in particular) may be obtained through the use of entangled states in a ghost imaging configuration has been investigated. The resiliency of such a system in the presence of transmission impairments that necessarily accompany sensors in a tactical environment, such as large optical loss, atmospheric turbulence and scattering has been considered. The prospective imaging sensor based on quantum entangled states has been compared with respect to a similar sensor based on classical states in terms of its expected performance. Experiments concerned with the generation of ghost images with nondegenerate pulsed sources of entangled photons as well as with tri-photons have been carried out. Prospects for multiple photon absorption by coupled quantum wells have also been studied.
