Quantum Imaging:
Coincidence, or ghost, imaging is a technique that uses two
correlated optical fields to form an image
of an object. Using photons entangled from parametric down conversion, we
find that these photons allow high-contrast, high-resolution imaging to be
performed at any distance from
the original light source. We've demonstrated this fact by forming
coincidence images in the
near and far fields of an
entangled photon source, noting that the product of the resolutions of these
images is a factor of 3 better than that which is allowed by classical
diffraction theory.
