Quantum imaging can be used in various scientific disciplines including materials science, chemistry, and biology. This technology will represent an early-stage practical quantum sensing application that utilizes an understanding in quantum information science to maximize the information contents.
Super-resolution imaging reveals minute structures visually with an imaging resolution well below the common classical imaging limit of Rayleigh diffraction (about the wavelength of the probe light). For example, Sandia proved that it is technically possible to reveal 60 nm structure features of a solid-state surface when 780 nm wavelength light is used for imaging. Such a visual inspection capability may provide a breakthrough in diagnostics and analysis of chemical processes, biological processes, and material details on various samples of interest. To realize such an unprecedented capability, Sandia invented a method that uses entangled squeezed quantum light and an associated quantum measurement scheme to maximize the information contents in limited imaging resources (i.e., the number of photons used in imaging).
