Quantum Imaging beyond the Diffraction Limit by Optical Centroid Measurements

Abstract

I propose a quantum imaging method that can beat the Rayleigh-Abbe diffraction limit and achieve de Broglie resolution without requiring a multi-photon absorber or coincidence detection. Using the same non-classical states of light as those for quantum lithography, the proposed method requires only optical intensity measurements, followed by image post-processing, to produce the same complex quantum interference patterns as those in quantum lithography. The method is expected to be experimentally realizable using current technology.
