Phys. Rev. Lett. 92, 033601 (2004) [4 pages]Quantum and Classical Coincidence ImagingSee Also: Publisher's Note Received 21 July 2003; published 22 January 2004; publisher error corrected 30 January 2004 Coincidence, or ghost, imaging is a technique that uses two correlated optical fields to form an image of an object. In this work we identify aspects of coincidence imaging which can be performed with classically correlated light sources and aspects which require quantum entanglement. We find that entangled photons allow high-contrast, high-resolution imaging to be performed at any distance from the light source. We demonstrate this fact by forming ghost 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. © 2004 The American Physical Society URL:
