DOI: 10.1103/physreva.101.022323
Abstract: It has been recently shown that an interferometric measurement may allow for sub-wavelength resolution of incoherent light. Whereas this holds for noiseless detectors, one could expect that the resolution is in practice limited by signal-to-noise… read more here.
