Quantum Information Inspires New Superresolution Techniques for Incoherent Imaging
The wave and particle natures of light limit the resolution of incoherent imaging via diffraction and photon shot noise. Quantum information theory can take both into account and reveal the ultimate resolution limits. Our group recently discovered that, surprisingly, the ultimate quantum limit to the resolution of sub-Rayleigh incoherent sources is much higher than previously realized. We have further invented optical techniques that can achieve the limit and are realizable simply by far-field linear optics and intensity measurements. Four experimental demonstrations have since been reported. We envision our techniques to benefit both observational astronomy and fluorescence microscopy.
